➷ 3x + 7 / 4x + 7 = 4/5

Cross multiply:

5(3x + 7) = 4(4x + 7)

Expand:

15x + 35 = 16x + 28

Subtract 28 from both sides:

15x + 7 = 16x

Subtract 15x from both sides:

x = 7

4(7) = 28

Dom is 28 years old

marusya05 [52]

You are given that all three sides of both the triangles are "approximately equal"

This means the answer is D. SSS (Side-Side-Side)

It can't be A. because S-A-S means side-angle-side and these are not the "givens"

It can't be B. because A-S-A means angle-side-angle and these are not the "givens"

It can't be C. because A-A-A means angle-angle-angle and these are not the "givens"

Hope this helped!
