Find the perimeter of a regular pentagon with sides of (3x + 5).

5 (3x + 5) or 15x + 25

Step-by-step 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 + 5)

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

P = 15x + 25
