Question

Determine the value of x that would make quadrilateral LMNO a parallelogram.

3
9
11
18​

Answer 1

9

Explanation:

Answer 2

Answer:
x=9
Explanation:
Diagonals of a parallelogram bisect each other. For quadrilateral LMNO to be a parallelogram, LP must equal PN, and OP must equal PM.
Set OP equal to PM and solve for x.
PM=OP
3x-9=18
Add 9 to both sides.
3x=27
Divide both sides by 3.
x=9
