Answer:
7
Step-by-step explanation:
AB//CD (Opposite sides of parallelogram are parallel)
Angle A + Angle B = 180 (Sum of interior angles=180)
138 + 7x - 7 = 180
7x - 7 = 180 - 138
7x = 42 + 7
7x = 49
x = 49/7
x = 7
<span>let x is the number
2x + 18 = 9 - 4x
If solve for x
2x +4x = 9 -18
6x = -9
x = -9/6
x = -3/2</span>
diagonal for rectangle= sqrt( A^2 +b^2)
diagonal for square = sqrt(2) * Side
rectangle diagonal = sqrt (14^2+7^2) = 15.65 inches
square diagonal = sqrt(2) * 7 = 9.90 inches
9.9 *2 = 19.8
the diagonal of the rectangle is not two times the length of the square
Answer: Choice D

This matches with <u>choice D as the final answer.</u>
Keep in mind that we can only subtract fractions when the denominator is the same. The rule is
