<h3>Part A</h3>
<u>Factoring the area:</u>
- 4x² + 20x + 25 =
- (2x)² + 2*2x*5 + 5² =
- (2x + 5)²
<u>The length of the side is:</u>
<h3>Part 2</h3>
<u>Factoring the area:</u>
- 4x² − 9y²=
- (2x)² - (3y)² =
- (2x + 3y)(2x - 3y)
<u>The sides of the rectangle are:</u>

Answer:
-7 is your answer
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other.
4 + y = -3
Subtract 4 from both sides
4 (-4) + y = -3 (-4)
y = -3 - 4
y = -7
-7, or (D) is your answer
