B as when you look at the X coordinate line you can see how the parabola goes between when x is both -1 and when it is -4.
The Expression for the Area a of the rectangle as a function of length L is given by A(L) = 12L - L^2 .
Let,
length, L, and the width, W, are components that help determine the area, A, and the perimeter, P of the rectangle. These are given by the following equations
A=LW
P=2L+2W
Given,
Perimeter of the Rectangle = 24m.
We are asked to express the perimeter of the rectangle as a function of the length, L, of one of its sides.
We will first set up the equation of the Perimeter of the rectangle. We can let the width of the rectangle be W.
P = 2L+2W
24 = 2L+2W
12 = L+W
W = 12-L
Since we want to express the Area as a function of L, we have to find the value of W in terms of L. This is so we can eliminate the width in the equation for the Area. The Area as a function of L is as follows.
A(L, W) = LW
A(L) = L(12-L)
A(L) = 12L-L^2
Therefore, the Area as a function of L is given by A(L) = 12L-L^2.

The answer to your problem is 5.5 because if you do this problem (5.5 + 5.5) it is 11
Answer:
k = - 1
Step-by-step explanation:
If (x - 5) is a factor of p(x) then p(5) = 0
p(5) = 5³ - 6(5)² + 5k + 30 = 0 , that is
125 - 150 + 5k + 30 = 0
5 + 5k = 0 ( subtract 5 from both sides )
5k = - 5 ( divide both sides by 5 )
k = - 1
