The perimeter of a rectangle is given by the following formula: P = 2W + 2L
To solve this formula for W, the goal is to isolate this variable to one side of the equation such that the width of the rectangle (W) can be solved when given its perimeter (P) and length (L).
P = 2W + 2L
subtract 2L from both sides of the equation
P - 2L = 2W + 2L - 2L
P - 2L = 2W
divide both sides of the equation by 2
(P - 2L)/2 = (2W)/2
(P - 2L)/2 = (2/2)W
(P - 2L)/2 = (1)W
(P - 2L)/2 = W
Thus, given that the perimeter (P) of a rectangle is defined by P = 2W + 2L ,
then its width (W) is given by W = (P - 2L)/2

Ummmmmmm
Step-by-step explanation:
(or 0.5) divided by 8 is 0.0625
First you must set up the equation.
Then, divide 0.5 by 8
0.0625

Answer:
The answer would be (3,-4) This is because if you replace the variables with the numbers and solve the equation it will come out 0=0
So, lets solve.
y+4=-5(x-3)
-4+4=-5(3-3)
0=-5x0
0=0
So therefore the correct answer will be (3,-4)
Hope this helped
