Question

In parallelogram ABCD, if AO = 4x + 12 and OC = 5x – 6 what is the

****length of AC (be careful)

Answer 1

Explanation:

The sides of a parallelogram are equal. If O is the midpoint of its diagonal AC, them AO+OC = AC

Given

AO = 4x + 12 and

OC = 5x – 6

Required

AC

AC = 4x+12 + 5x-6

AC = 4x+5x+12-6

AC = 9x+6

Hence the length of AC is 9x+6
