Question

If one side of a regular pentagon is represented by 3x + 1 , what is the perimeter of the pentagon?

Answer 1

5(3x+1) or 15x+5

Explanation:

A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:

P = 5(3x +1)

Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:

P = 15x + 5
