The expressions for the width, W, and area, A, of the rectangle in terms of L are:
- W =
- L - A =
The expression for the perimeter of a rectangle is given as:
P = 2(L + W)
where L is its length and W its width
a. Given that the perimeter of the rectangle is 13 feet, then;
13 = 2(L + W)
divide through by 2
= L + W
So that;
W = - L
The required formula for the width as a function of L is: W = - L
b. Area of a rectangle can be expressed as;
A = L * W
substitute the expression for width in that of area to have
A = L * ( - L)
= L - 
A =
The expression for the area A is: A =

Answer:
Yes
Step-by-step explanation:
12x minus -3x is the same as adding two positives. That gives us 15x. 4 - 5 is -1. Putting the two simplified parts of the expression together, we get 15x - 1. Mason is correct.

Answer:
(4,-1)
Step-by-step explanation:
the graph goes up or down by 2 each time so 2x2=4
then half of -2 is -1
