Write the equation and solve the problem. the length of a rectangle is four less than twice the width. if the perimeter is 34, find the length and the width.

The formula of a perimeter of a rectangle:

P = 2(l + w)

We have P = 34 and l = 2w - 4.

Substitute:

2(2w - 4 + w) = 34

2(3w - 4) = 34       use distributive property

(2)(3w) + (2)(-4) = 34

6w - 8 = 34       add 8 to both sides

6w = 42      divide both sides by 6

w = 7

l = 2w - 4 → l = 2(7) - 4 = 14 - 4 = 10

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.
