@Hero can you help me on this?

OpenStudy (whpalmer4):

|dw:1360377955938:dw| We know the two opposite sides, and we know the length of the midsegment, which is the average of the other two. \[\frac{(5)+(2x+7)}{2} = 6x-24\] Solve for x, and then you can evaluate the length of the unknown base.

OpenStudy (anonymous):

OpenStudy (anonymous):
