2. The width of a rectangle is 12 inches less than its length. The perimeter of the rect- angle is 56 inches. Find the length and width of the rectangle.

Since the perimeter is 56 inches we can solve for the lenght with this equation:

And solving for the length we got:

So then the lenght = 16 inhes and the width of 12 inches

Step-by-step explanation:

For a rectangle of width 12 inches and lenght y inches we know that the perimeter is given by:

Since the perimeter is 56 inches we can solve for the lenght with this equation:

And solving for the length we got:

So then the lenght = 16 inhes and the width of 12 inches

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
