➷ Opposite lengths in a parallelogram are equal

Therefore:

2x - 9 = x + 8

Add 9 to both sides:

2x = x + 17

Subtract x from both sides:

x = 17

Your answer is option c.

Answer 2

C x=17

Explanation:

The top and bottom sides have to be equal for the quadrilateral to be a parallelogram

2x-9 = x+8

Subtract x from each side

2x-9-x = x+8-x

x-9 = 8

Add 9 to each side

x-9+9=8+9

x=17
