Answer:

-a + 40 = 28, a = 12

Step-by-step explanation:

If he takes the opposite of his age, that means the current number is negative. We can get -a + 40 = 28, we can then simplify by subtracting both sides by 40 and getting -a = -12 which is equal to a = 12

Answer:

7.6

Step-by-step explanation:

From the graph, we know the lengths of two legs.

  a = 3

  b = 7

Knowing this, we can use the Pythagorean Theorem to solve for c, the hypotenuse. (remember,  a^2 + b^2 = c^2)

c = √a2 + √b2  

= √(7)2 + √(3)2

= √49 + √9

= √58

= 7.6

Answer:7.6

Step-by-step explanation:

Answer:  17.28 cm^2

Step-by-step explanation:

You can also use AC as the base, then BE will be the height to that.

Assuming you want your answer in cm^2, then (7.2*4.8)/2 = 17.28 cm^2.

Answer:

2160mm

Step-by-step explanation:

Recall that to find the area of a triangle, you need to follow the formula:

A = 1/2 * b * h

But first we need to convert the cm to mm, or else our calculations will be incorrect:

9.6 cm = 96 mm

4.8 cm = 48 mm

Let's cut the triangle into two pieces to make it easier for us to find the area. We'll start with triangle ACD:

A = 1/2 * 36 * 72

A = 1/2 * 2592

A = 1296 mm

Now that we have the area for triangle ACD, let's move on to try to find the area of triangle DCB:

A = 1/2 * 36 * 48

A = 1/2 * 1728

A = 864

It's time to add them up:

(DCB) 864 + (ACD) 1296 = 2160

The area of the triangle is 2160 mm.

Answer:

(x-2) (x+6)

Step-by-step explanation:

If it is written like this:

[tex]x^{2} +4x + 3 = 15[/tex]

To focus on the equation on the left rewrite the equation equal to the value of zero.

(x-2) (x +6) = 0

The answer is (x-2) (x+6)

Answer:

These two figures are not congruent.

Step-by-step explanation:

The definition of congruence is, "In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.", now knowing this we next take a look at the figures.

Coordinates (A, E) do not match up with the bottom figures (P, T). The next coordinates (E, D) also don't match up with coordinates (T, S). Coordinates (A, B) and (P, Q) don't match up together either. (B, O), (Q, R), (O, D), or (R, S) also do not match up if you look closely at them. Now you can conclude that although these two figures may look alike at first glance, their points are put in different places showing that they aren't the same in shape and size; meaning they are not congruent.

Two figures are congruent if their dimensions are equal

ABCDE = PQRST therefore, ABCDE ≅ PQRST, by the definition of congruency

Reason:

The coordinates of pentagon ABCDE are;

A(-2, 8), E(4, 8), D(6, 2), C(-2, 2), B(-4, 6)

The coordinates of pentagon PQRST are;

P(-3, 0), T(3, 0), S(5, -6), R(-3, -6), Q(-5, -2)

By performing the vector translation of [tex]\dbinom {1}{8}[/tex], to PQRST, we have;

P(-3 + 1, 0 + 8) = (-2, 8) = Coordinates of A

T(3 + 1, 0 + 8) = (4, 8) = Coordinates of E

S(5 + 1, -6 + 8) = (6, 2) = = Coordinates of D

R(-3 + 1, -6 + 8) = (-2, 2) = = Coordinates of C

Q(-5 + 1, -2 + 8) = (-4, 6) = = Coordinates of B

Given that a translation is a rigid transformation and  that by performing a translation transformation of [tex]\dbinom {1}{8}[/tex], on PQRST gives ABCDE, we have that the dimensions of the pentagon ABCDE = The dimensions of the pentagon PQRST, we have;

ABCDE = PQRST

Therefore;

ABCDE ≅ PQRST, by the definition of congruency

Answer:

3

Step-by-step explanation:

You might just think that I subtracted but on the triangle the last side is the base which is always smaller.

Answer: The answers are 4, 8, 10

To solve, you must use the Triangle Inequality Rule -

Subtract 7-4=3; therefore, the 3rd side must be greater than 3

Add 7+4=11; therefore, the 3rd side must also be less than 11

Any number greater than 3 or less than 11 would be correct.

Step-by-step explanation:

Answer:

1. The slope of line l1 is -1/2

2. The slope of l2 is 2

Step-by-step explanation:

Perpendicular lines have opposite inverse slopes. The inverse of 2 is 1/2 and the opposite is -2. Therefore the opposite inverse slope of the perpendicular line, l1, is -1/2

When two lines are parallel, the slopes are the same. l2 is parallel to l therefore, they share the same slope.

Answer:

x=7,  angle a= 45 degrees, angle b= 65 degrees

Step-by-step explanation:

All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65

Answer:

x = 7

m∠B = 65

m∠A = 45

Step-by-step explanation:

So we know that the inside of a triangle equals 180º. So we have one angle already, 70º, so what we can do is subtract 70 from 180.

180 - 70 = 110

Now we can set both equations equal to 110.

2 + 9x + 7x - 4 = 110

Now simplify.

2 + 9x + 7x - 4 = 110

2 + 16x - 4 = 110

16x - 2 = 110

      +2       +2

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

16x = 112

÷16       ÷16

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

x = 7

So now you can just plug 7 in for x to check your answers

2 + 9(7) = 65

7(7) - 4 = 45

65 + 45 + 70 = 180
