He length of a rectangle is 12 in. and the perimeter is 56 in. find the width of the rectangle. a. 21 in. b. 22 in. c. 32 in. d. 16 in.

The formula of a perimeter of rectangle:

P = 2(w + l)

We have l = 12 in and P = 56 in.

Substitute:

2(w + 12) = 56      use distributive property

(2)(w) + (2)(12) = 56

2w + 24 = 56       subtract 24 from both sides

2w = 32      divide both sides by 2

w = 16

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

answer:

x=17
