<h3>Answer:  12</h3>

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

Explanation:

You can use the AAS (angle angle side) theorem to prove that triangle ABD is congruent to triangle CBD.

From there, we can then say that AD and DC are the same length

AD = DC

3y+6 = 5y-18

3y-5y = -18-6

-2y = -24

y = (-24)/(-2)

y = 12

Given that f(x) = 2x + 1 and g(x) = −5x + 2, solve for f(g(x)) when x = 3.
ANTONII [103]
f(x)=2x+1 \\&#10;g(x)=-5x+2 \\ \\&#10;f(g(x))=2(-5x+2)+1=-10x+4+1=-10x+5 \\&#10;f(g(3))=-10 \times 3+5=-30+5=-25 \\&#10;\boxed{f(g(3))=-25}

The answer is C.

In this diagram, BAC – EDF. If the
puteri [66]
The triangles are congruent. So.

Triangle ABC is 24 inch^2 and BC is 4 inches.
The area of a triangle is 0.5 x base x height. The will be 12 because 12 x 4 x 0.5 which equals 24.

Triangle DEF is half the size of ABC because bc is 4 and EF is 2 showing it’s half. This then means the height will be half which then mean it will be 6.

This then means we can use the equation to work it out. So. 6 x 0.5 x 2 = 6in^2

The answer is 6inches^2
