= x·[2(x²- 4x + 4) + 3(x² + 6x + 9) - x² + 5x]

= x(2x² - 8x + 8 + 3x² + 18x + 27 - x² + 5x)

= x(4x² + 15x + 35)

Answer:

y = -1

Step-by-step explanation:

Sides marked with the same marking are congruent, so we have two equations:

3x -y = 16
2x +y = 9

Adding the equations gives ...

5x = 25

x = 5 . . . . . . divide by 5

Then the second equation tells us ...

y = 9 -2x = 9 -2(5) = -1

The value of y is -1.
