The perimeter of a rectangle is 80 inches. The length of the rectangle is three times its width. How wide is the rectangle?

The width is 10 inches.

Step-by-step explanation: Perimeter = 2(w + L)

the length is 3 times width, so substitute 3w for L in the equation.

2(w +3w) = 80

2(4w) =80

8w = 80

w = 10

the Length would be 3(10) = 30 inches

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
