Question

find the perimeter. simplify your answer. 7c - 10 7c - 10 7c 10c - 4

Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a polygon is the sum of the lengths of its sides. So $P=(7c - 10)+(7c - 10)+7c+(10c - 4)$.

Step2: Combine like - terms

First, combine the $c$ terms: $7c+7c + 7c+10c=31c$. Then combine the constant terms: $-10-10 - 4=-24$.

Answer:

$31c-24$
