Answer:
40
Step-by-step explanation:
The parallelograms are similar, so their corresponding sides are proportional. Write a proportion:
12 / 30 = 16 / PQ
Cross multiply:
12 PQ = 480
Solve for PQ:
PQ = 40
C -20/27 because 5x-8= -40 and 9x6= 54 and u divide both numbers by two and get C
X + y = -3
<u>x - y = 13</u>
<u>2x</u> = <u>10</u>
2 2
x = 5
x + y = -3
5 + y = -3
<u>- 5 - 5</u>
y = -8
(x, y) = (5, -8)
Is 8 I am not sure at all
