Are you sure the question is correct? From what I see, you already got the answers...
OpenStudy (tukitw):
But isn't DE = 3t - 2 and AP = 4t + 4?
OpenStudy (tukitw):
I think you need to find t first
OpenStudy (tukitw):
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
