Answer:

x = 2

y = 9

Step-by-step explanation:

Opposite sides of a parallelogram are the same length. This relation is used to make equations with the given side lengths.

Top and Bottom

4x +20 = x +26

3x = 6 . . . . . . . . . . . subtract x+20 from both sides

x = 2 . . . . . . . . . divide by 3

Left and Right

7y = 6y + 9

y = 9 . . . . . . . . . subtract 6y from both sides

Answer:

4x^2 + 4 - 5x + x - 2x^2 + 8

= (4x^2 - 2x^2) + (x - 5x) + (4 + 8)

= 2x^2 - 4x + 12

=> D is correct

2x^2 + 6x - 7x + 8 - 3x^2 + 1

= (2x^2 - 3x^2) + (6x - 7x) + (1 + 8)

= -x^2 - x + 9

=> C is correct

B is correct (4 and 3)

Hope this helps!
