Answer:
x = 8 units
Explanation:
A rhombus is a quadrilateral which has four equal sides.
This means that for MNOP to be a rhombus:
MN = NO = OP = MP
We have:
MN = 6x - 7
ON = 4x + 9
Equate the two lengths and solve for x as follows:
MN = ON
6x - 7 = 4x + 9
6x - 4x = 9 + 7
2x = 16
x = 16/2
x = 8 units
Hope this helps :)
