Question

A regular pentagon has a perimeter of 15x+35
What is the length of one side of the pentagon?

Answer 1

-3.5 or -7/2

Explanation:

Pentagons have five sides, so 15x+35

15x+35=5

subtract 35

15x+35-35=5x-35

simplify

15x=5x-35

subtract 5x

15x-5x=5x-35-5x

simplify

10x=-35

divide by 10

`(10x)/(10)=(-35)/(10)`

simplify

`x=-(7)/(2)` or also -3.5
