Question

Given ∆QRS≅∆TUV, QS=4v+3, and TV=7v−9, find the length of QS and TV.?

a.
37
b.
4
c.
19
d.
20

Answer 1

I did the math and it is 19

Answer 2

If ∆QRS≅∆TUV, Their corresponding sides would be equal so,
QS = TV
4v + 3 = 7v - 9
7v - 4v = 3 + 9
3v = 12
v = 4

Now, QS = TV = 4(4) + 3 = 16 + 3 = 19

In short, Your Answer would be Option C

Hope this helps!
