Question

Given the median QR and trapezoid MNPO, what is the value of x?

Answer 1

7

Explanation:

I took the test

Answer 2

7

Explanation:

Since the median is equal to the sum of the two bases divided by two , we have: QR=(5x-14+17)/2; but QR= x+12, so x+12=(5x+3)/2; 2(x+12)=5x+3; 2x+24=5x+3; ordering 5x+3=2x+24; 5x-2x=24-3; 3x=21 so x=21/3 = 7
