<u>Answer</u>

A. y – 1 = 0


<u>Explanation</u>

5x – 8y + 3 = 5x – 7y + 2

First put the like terms together.

5x - 5x -8y + 7y + 3 - 2 = 0

0x - y + 1 = 0

-y + 1 = 0

Multiplying both sides of the equation by -1.

-1(-y + 1) = -1 × 0

y - 1 = 0

Let p= x^2-7.
Advocard [28]

Since p = x² - 7, you can substitute/plug in p for x² - 7

So:

(x² - 7)² - 4x² + 28 = 5

(p)² - 4x² + 28 = 5      You can factor out -4 from (-4x² + 28)

p² - 4(x² - 7) = 5        Plug in p

p² - 4p = 5        Subtract 5

p² - 4p - 5 = 0        Your answer is C

Since the sum of the angles equal to 720, you have to add all the angles to add to 720 and then solve for x, in which would look like this (x+2)+(x-4)+(x+6)+(x-3)+(x+7)+(x-8)=720, which is simplified to (6x)=720, in which will make x=120. Next, since its angle E, you plug in tha x value, (120+6), in which the ANSWER IS 126 DEGREES
