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:

Answer 2

3x + 7

Explanation:

Recall that a regular pentagon has 5 sides of equal length

If the perimeter of the pentagon is given, then the length of each side is simply the perimeter divide by 5 or,

length of each side

= perimeter ÷ 5

= (15x + 35) ÷ 5

= (15/5) x + (35/5)

= 3x + 7
