Question

3. A regular pentagon has a perimeter of 10x + 15. What is the length of che side?

A. x+2

B. 2x-3

C. 2x + 3

D. 10(x + 2)

How do I get the answer??

Answer 1

C

Explanation:

A pentagon has 5 sides. Given that it is a regular pentagon, these 5 sides are equal.

The perimeter is the total length of all the sides of the pentagon. Since these 5 sides are all equal, we can divide the perimeter by 5 to obtain the length of a side of the pentagon.

Perimeter= 10x +15

Length of each side

= (10x +15) ÷5

= 2x +3
