Regular pentagon means the shape with 5 sides which their lengths are equal to each other.
so, if the total perimeter of the pentagon is 10s - 20,
we can find the length of each side by dividing it by 5.
(10s - 20) / 5
we can expand this equation by dividing each number in the bracket by 5
= 2s - 4
Therefore, the answer should be D.

Answer:
D. 4 jump ropes, 3 people, 15 friends
Step-by-step explanation:
In order to answer the question how many friends could play, you need to be able to determine the smaller of ...
- (number of ropes) × (friends per rope)
- number of friends
You can find the first of these numbers using the values of answer A, but if the number of Franklin's friends is smaller than 12, then you need to know that in order to properly answer the question. Hence, we believe you need to know ...
- the number of jump ropes
- the number of friends per rope
- the number of friends
