Answer:
x + 5
Step-by-step explanation:
A = LW
W = A/L
W = (x^2 + 16x + 55)/(x + 11)
W = [(x + 11)(x + 5)]/(x + 11)
W = x + 5

The Length of the rectangle is 18 unit.
<h3>
What is the Perimeter of a Rectangle?</h3>
Perimeter of rectangle = 2(length + width)
Given the following:
Let x represent the width of the rectangle
Width of the rectangle = x
Length of the rectangle = 4x + 6
Perimeter of rectangle = 42 units
Therefore, we would write the following equation to find x based on the formula for finding the perimeter of a rectangle:
2(4x + 6 + x) = 42
2(5x + 6) = 42
10x + 12 = 42
10x = 42 - 12
10x = 30
10x/10 = 30/10
x = 3
The width (x) = 3.
Length of the rectangle = 4(3) + 6
Length of the rectangle = 18 unit.

Answer:
5, 29 will both blank boxes
Step-by-step explanation:
the product of (4z^2 + 7z – 8) and (–z + 3)
(4z² + 7z – 8)(–z + 3)
-z(4z² + 7z – 8) + 3(4z² + 7z – 8)
-4z³-7z²+8z+12z²+21z-24
choose like terms
-4z³-7z²+12z²+8z+21z-24
-4z³+5z²+29z-24
