Answer:

x = -4

Step-by-step explanation:

[tex] - 3x = 12[/tex]

Lets divide both the sides by -3.

[tex] = > \frac{ - 3x}{ - 3} = \frac{12}{ - 3} [/tex]

[tex] = > x = - 4[/tex]

x= -4

-3x=12

divide x by -3 and do the same on the other side

12÷(-3)= -4

hence, x= -4

Answer:

Yes

Step-by-step explanation:

She just distributed the 3 to the (2+x). If you multiple each by 3, you'll get 6+3x.

Answer:

Yes

Step-by-step explanation:

3 and 6 are multiples so yes they are equivalent

The polygons are similar.

This is because dividing the corresponding sides forms the same ratio, as shown by the three equations below

35/28 = 1.25

25/20 = 1.25

(15.5)/(12.4) = 1.25

So the larger figure on the right has side lengths that are 1.25 times larger compared to the corresponding sides of the figure on the left.

You'll need to flip the figure on the left so that the side labeled "20" is along the top, and the "28" is along the bottom.

After this flip happens, also note that the angle arc markings match up. The bottom pairs of angles of each figure are shown with a single arc, while the top angles are shown as double arcs. This helps visually show which angles pair up and are congruent to one another.

Because we have similar proportions as discussed earlier, and congruent pairs of angles like this, this shows the two figures are similar quadrilaterals. The one on the right is simply an enlarged scaled up copy of the figure on the left.

Answer:

X=8

Step-by-step explanation:

well, we are trying to find one of the legs of the triangle, using the equation from the Pythagorean Theorem we know that A^2+B^2=C^2

A^2+B^2=C^2, we know that 6^2 times x^2 MUST equal 10^2.

So using the equation, below i show you how to get the value of x.

A^2+B^2=C^2

6^2+B^2=10^2

36+B^2=100

36-36+B^2=100-36

B^2=64

now, B^2 is equal to 64, but we need to find the square root of 64 to get B, or as listed in the question, x.

To save time, ill just tell you, the square root of 64 is 8.

SO

X=8

================================================

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (8-6)/(2-5)

m = (2)/(-3)

m = -2/3

As you can see, we subtract the y coordinates together. We also subtract the x values together in the same order. If the order is mixed up, then you'll get the wrong sign for the final answer.

The slope is equal to rise over run. Think of "rise" as "change in y", which explains the difference in y values. The run is equal to the change in x, which is the difference in x values.

The area of the mirror with the frame is approximately 226.98 in².

What is an area?

An area is a two-dimensional measurement of the extent or size of a surface. It is a mathematical concept used to describe the amount of space inside a closed boundary, usually measured in square units.

the area of a square can be calculated by multiplying the length of one side by itself. The area of a rectangle can be calculated by multiplying its length and width. Similarly, the area of a circle can be calculated by using the formula πr², where "r" is the radius of the circle. Areas can be used to describe the size of physical objects or spaces

The radius of the mirror can be calculated by subtracting the width of the frame from the diameter:

Radius = (17 in / 2) - (1 in / 2) = 8 in

The area of the mirror (including the frame) can be calculated as:

Area = π * (radius + width of frame)²

Area = 3.14 * (8.5 in)²

Area ≈ 226.98 in²

Rounding to the nearest hundredth, the area of the mirror with the frame is approximately 226.98 in².

Answer:

471.25

Step-by-step explanation:

A volume of a box is equal to length x width x height (abbreviated lwh). The given was: 14 & 1/2 inches long, 5 inches high, and 6 1/2 inches wide. So, all you have to do is multiply the given (I know it sounds too easy, but that's it):

14.5 * 5 * 6.5 = 471.25

So, the volume of the box is 471.25 inches cubed.
