Jake cuts out five pointed stars. They are different sizes, but they all have the same shape. The size lengths within each star are the same. To find the perimeter of each star. Jake uses the expression 12L + 1/2 - 4L - 8.5 + 2L + 8, where L is the side length of the star. Find the perimeter of a star with side length 6 inches

Perimeter of the star = 60 inches

Step-by-step explanation:

Given:

12L + 1/2 - 4L - 8.5 + 2L + 8

Where,

L = side length of the star

Find the perimeter of a star with side length 6 inches

L = 6 inches

Perimeter of the star = 12L + 1/2 - 4L - 8.5 + 2L + 8

= 12(6) + 1/2 - 4(6) - 8.5 + 2(6) + 8

= 72 + 0.5 - 24 - 8.5 + 12 + 8

= 60 inches

Perimeter of the star = 60 inches

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
