Question

Rise the midpoint of QS If QR = 4x and RS = x + 6, what is QR?

Answer 1

QR = 8

Explanation:

4x x + 6

Q ------------ R ------------S

find: QR

QR = QS

4x = x + 6

4x - x = 6

3x = 6

x = 6/3

x = 2

solve for QR: solve for QS:

QR = 4x QS = x + 6

QR = 4(2) QS = 2 + 6

QR = 8 QS = 8
