Question
g) écris une expression algébrique simplifiée qui représente le périmètre du triangle.
Step1: Recall perimeter formula
The perimeter $P$ of a triangle is the sum of the lengths of its sides. So $P=(2x + 1)+(3x-2)+(x + 3)$.
Step2: Remove parentheses
$P=2x + 1+3x-2+x + 3$.
Step3: Combine like - terms
Combine the $x$ terms: $2x+3x+x=(2 + 3+1)x=6x$. Combine the constant terms: $1-2 + 3=2$. So $P=6x+2$.
