Question

the perimeter of the triangle is. 1 5x+1 5x 5x+3

Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a triangle is the sum of the lengths of its sides. So $P=(x + 2)+(2x-1)+2x$.

Step2: Combine like - terms

First, add the $x$ - terms: $x+2x + 2x=5x$. Then add the constant terms: $2-1 = 1$. So $P=5x + 1$.

Answer:

$5x + 1$
