Okay :)

i'm assuming QRS and TUV are triangles. are they?

anonymous · Answer

since the problem says that the triangles are equal we can say that 3v+2=7v-6 because of CPCTC

anonymous · Answer

And then what do i do?

anonymous · Answer

if we solve 3v+2=7v-6 we get v=2. If you plug 2 back into the original equations 3v+2 and 7v-6 we get they equal 8. So your answer is C 8. Did that make sense?
