Joan is building a sandbox in the shape of a regular pentagon. The perimeter of the pentagon is 35y4 – 65x3 inches. What is the length of one side of the sandbox? 5y – 9 inches 5y4 – 9x3 inches 7y – 13 inches 7y4 – 13x3 inches

D. 7y^4 - 13x^3 inches

Step-by-step explanation:

given that Joan is building a sandbox in the shape of a regular pentagon.

The perimeter of the pentagon is

inches.

Since regular pentagon we know that all sides are equal and there are totally five sides.

Perimeter of regular pentagon = 5*side

= 5a where a = length of side

Equate 5a to given perimeter to get

divide by 5

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

30,40,50 is correct answer
