Answer 1

Are you sure the question is correct? From what I see, you already got the answers...

Answer 2

But isn't DE = 3t - 2 and AP = 4t + 4?

Answer 3

I think you need to find t first

Answer 4

By the midpoint theorem, AP = 2DE.
4t + 4 = 2(3t - 2)
4t + 4 = 6t - 4
2t = 8
t = 4
DE = 3(4) - 2 = 10
AP = 2DE = 20

Answer 5

Oh,II see. that really helped a lot. thanks!
