if a = -5 find the value of 3a ²

Answer:

- 7x

Step-by-step explanation:

Given

(x - 4)(x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 3) - 4(x - 3) ← distribute both parenthesis

= x² - 3x - 4x +  12 ← collect like terms

= x² - 7x + 12

with middle term = - 7x

Answer:

Step-by-step explanation:

= x(x-3) - 4(x-3)

= x²-3x - 4x + 12

= x² -7x +12

So -7x is the middle term

Answer:

Picture is down below

Step-by-step explanation:

When you are doing this question you would just graph the points (-4,4) and (4,4) so we would get a width of 8 and you need an area of 8 so the height would just be 1 since the area of a rectangle is l times w. So when you graph it, it would look like this. And the coordinate points would be (-4,4), (4,4), (-4,3),(4,3).

Answer:

Answer is (-4,4), (4,4), (-4,3),(4,3).

Step-by-step explanation:

(-4,4), (4,4), (-4,3),(4,3).

Answer:

I agree with Jada

Step-by-step explanation:

So first you would find the area of one of the faces and it is 100 and then you would multiply the area of one face by 6 because there are 6 faces so you would get 600 inches so Jada would be right

Answer:

Jada is correct in this situation.

Step-by-step explanation: Noah's math is not correct. He goes from 6 times 10^2 to 60^2, which you cannot do. You first must do the exponents (10^2=100) and then multiply it by 6. Jada's method should be similar to that.

Answer:

[tex]\bar X= \frac{\sum_{i=1}^n X_i}{n}[/tex]

The reason is because we assume that each week have the same weight and replacing we got:

[tex]\bar X= \frac{190+163+327+205}{4}= 221.25[/tex]

And the best option would be:

D. 221.25

Step-by-step explanation:

For this case we have the following data given

Week       1       2         3       4

Minutes  190   163   327   205

For this case we can find the mean with the following formula:

[tex]\bar X= \frac{\sum_{i=1}^n X_i}{n}[/tex]

The reason is because we assume that each week have the same weight and replacing we got:

[tex]\bar X= \frac{190+163+327+205}{4}= 221.25[/tex]

And the best option would be:

D. 221.25

Answer: 603 dots

Step-by-step explanation:

Triangle always has 3 sides. Given that

Each new triangle shown below has one more dot per side than the previous triangle. That means if first term has 6 dot, the second term will have 9 dots and third has 12 dots.

The difference between first and the second is the same with the difference between third and the second. That is,

First term a = 6

Difference d = 3

Number of term n = 200

This is arithmetic progression. We can come up with a formula:

Tn = a + ( n - 1 )d

Substitute all the parameters into the formula

Tn = 6 + ( 200 - 1 )×3

Tn = 6 + 199×3

Tn = 6 + 597

Tn = 603 dots

Therefore, the total number of dots on the 200th triangle of this sequence is 603 dots.

Answer:

The second option (see attached image)

Step-by-step explanation:

You are looking for a box diagram that represents 9 units, and from those, clearly marked sections that contain 3/2 = 1.5 units.The idea is to count how many 1.5 units you have in 9 units.

The in the second diagram you see 9 boxes subdivided in half. Then outlined in red other smaller boxes of length 1.5 units. We can clearly see from the diagram that there are exactly 6 of these smaller 1.5 units red boxes to produce the total 9 unit object.

It's point A. 4 vertical units away from point M.

Answer: Point A

Step-by-step explanation:

Point M has the same x value as point A and point A is 4 units below it.

Answer:

4) 1/8

First shaded boxes = 4/7

Second shaded boxes = 1 out of 8 boxes are shaded = 1/8

Step-by-step explanation:

1/2x1/4=1/8

7X8=56

59-7=49

First shaded boxes = 4 out of 7 are shaded = 4/7

Second shaded boxes = 1 out of 8 boxes are shaded = 1/8

The fractional part of the game is left   [tex]\frac{7}{8}[/tex]  , total minutes of playing time 56 mins and playing time are left in the game is 49 mins .

A fraction represents a part of a whole or, more generally, any number of equal parts.

According to the question

Jackson is attending a lacrosse game that is halfway through the first quarter

i.e,  Game played = [tex]\frac{1}{2} *\frac{1}{4}[/tex]

       Game played = [tex]\frac{1}{8}[/tex]  

a) fractional part of the game is left

Game left  = 1 -  [tex]\frac{1}{8}[/tex]  (treated complete game as 1 )

                 =    [tex]\frac{7}{8}[/tex]  

b)  If 7 minutes of playing time have past,  

i.e  [tex]\frac{1}{8}[/tex]  part of game is completed in 7 mins

therefore,

1 whole will complete in 7*8 = 56 mins

c) Minutes of playing time are left in the game

As,

total time to complete the game - game played time

=  56 -  7

= 49 mins

as in the fraction of shading question

a) [tex]\frac{4}{7 } is shaded[/tex]

b) [tex]\frac{1}{8}[/tex] is shaded

Hence , the fractional part of the game is left   [tex]\frac{7}{8}[/tex]  , total minutes of playing time 56 mins and playing time are left in the game is 49 mins .

Answer:

[tex]\huge\boxed{y-3=-\frac{1}{2}(x-1)}[/tex]

Step-by-step explanation:

Point-slope is:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]m-\text{This represents the slope.}\\\\(x_1,y_1)-\text{This represents the point used in the equation.}[/tex]

We have to complete the point-slope equation of the line through (1,3) (5,1).

--------------------------------------------------------

We have a incomplete equation of the line.

[tex]y-3=m(x-x_1)[/tex]

We need to find the slope of the line, and the value of  [tex]x_1[/tex].

--------------------------------------------------------

It seems that the value of 3 was used to be [tex]y_1[/tex]. This means that the point [tex](1,3)[/tex] was used for the equation. This means that [tex]x_1[/tex] would have to be 1.

Slope is rise over run.

[tex]m=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given the points (1,3) and (5,1).

[tex]m=\frac{1-3}{5-1}=\frac{-2}{4}=\frac{-1}{2}=\boxed{-\frac{1}{2}}[/tex]

The slope is one-half.

--------------------------------------------------------

We now have enough information to complete the point-slope equation.

[tex]{\left \{ {{x_1=1} \atop {m=-\frac{1}{2} }} \right.}\\\\y-3=m(x-x_1)\rightarrow\boxed{y-3=-\frac{1}{2}(x-1)}[/tex]

Our final equation is:

[tex]y-3=-\frac{1}{2}(x-1)[/tex]

Answer:

x = 6

Step-by-step explanation:

First, add 8 to both sides.

4x - 8 = 16

4x - 8 + 8 = 16 + 8

4x = 24

Then, divide 4 from each side.

4x ÷ 4 = 24 ÷ 4

x = 6

Hope this helps.

Answer:

x = 6

Step-by-step explanation:

Well to solve for x in,

4x - 8 = 16

We use the commutative property which is the moving of numbers and variables to either side of the equation.

So 4x - 8 = 16

+8 to both sides

4x = 24

Divide 4 by both sides

x = 6

Thus,

x is 6.

Answer:

√13

Step-by-step explanation:

(-3, -2) (0, 0)

distance √(9 + 4) = √13

The distance from the origin to the point A is [tex]\sqrt{13}[/tex] unit.

Let, the co-ordinates of two points in 2D plane are [tex](x_{1} ,y_{1} )[/tex] & [tex](x_{2}, y_{2} )[/tex]

Then the distance between this two points be d (say)

Therefore, [tex]d=\sqrt{(x_{2}- x_{1}) ^{2}+ (y_{2} -y_{1} )^{2} }[/tex]

The co-ordinate of point A in the graph is (-3, -2)

The co-ordinate of origin is (0, 0)

∴ The distance between (0, 0) & (-3, -2) is = [tex]\sqrt{((-3)-0) ^{2}+ ((-2) -0 )^{2} }[/tex]

                                                                    = [tex]\sqrt{(-3)^{2}+(-2)^{2} }[/tex]

                                                                    = [tex]\sqrt{9+4}[/tex]

                                                                    = [tex]\sqrt{13}[/tex]

Answer:

Tossing two coins once.

Step-by-step explanation:

According to the diagram, there are just two outcomes: either H or T.

The spinner has three outcomes, and the cubes have 6 outcomes each, so we can eliminate the top two options.

If the person were just tossing one coin, the outcomes would be H or T, but there are more outcomes than that, so the diagram represents tossing two coins once.

Answer:

50°

Step-by-step explanation:

Recall that an inscribed angle is half the arc length. Since Angle A measures 50°, this means that the arc length of BC (the intercepted arc) is 100°.

Arc BC is also representative of Angle D. In other words, the measure of angle D is half of 100°.

Angle D = 50°.

Answer:

d = 50°

Step-by-step explanation:

Inside a circle we can have inscribed angles (angles with the three points on the circle). These angles are half the length of the arc they inscribe.

The arc BC is inscribed by the angle of 50°, so we have:

[tex]50 = mBC/2[/tex]

[tex]mBC = 100\°[/tex]

The angle d inscribes the arc BC, so we have:

[tex]d = mBC/2[/tex]

[tex]d = 100/2[/tex]

[tex]d = 50\°[/tex]
