Rectangle property, MK=NO=14. MO=-7x+7=MK=14. Solve for x: x=-1.
In a rectangle, opposite sides are congruent. Therefore, NO = MK = 14.
Since MO = -7x + 7, and M and K are the same point, we can substitute MK for MO:
14 = -7x + 7
Subtract 7 from both sides:
7 = -7x
Divide both sides by -7:
-1 = x
Therefore, x = -1.
Question:
Given rectangle KLMN below, NO=14. If MO=-7x+7, solve for x.
