Answer:

Length = 43 inches
Width = 12 inches

Step-by-step explanation:

Perimeter of a rectangle = 2 * ( L + W)

The length of a rectangle is 5 inches less than 4 times the width.

Assume the width is x. Length is:

4x - 5

Equation is therefore:

2 * (4x - 5 + x) = 110

4x - 5 + x = 110/2

5x - 5 = 55

5x = 55 + 5

x = 60/5

x = 12 inches

If width is 12 inches, then length is:

= 4x - 5

= 4 * 12 -5

= 43 inches

Answer:

B. -2

Step-by-step explanation:

-6x = 5x + 22

Put the like terms together, so subtract 5x from the right side. This will result in the new equation, -11x = 22

Now, divide by -11. This will result in the final equation, x = -2
