The perimeter of the triangle shown is 182 inches. find the length of each side.

5x=45, 7x+3=66, and 7x+8=71

Step-by-step explanation:

5x+7x+3+7x+8=182

Rearrange

5x+7x+7x+8+3=182

Add everything up

19x+11=182

Subtract 11 from both sides

19x=171

Divide both sides by 19

x=9

Plug x=9 into all spaces with x

5*9=45 , 7*9+3=66 , and 7*9+8=71

Voila!

good luck on ur quiz test or homework. have a good day : )

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
