Question

1. if a triangle has sides of length x, x + 1, and x - 2, what is the perimeter of the triangle in terms of x?

a. 3x - 3
b. 3x - 1
c. 3x + 1
d. 3x + 3

Explanation:

Step1: Recall the formula for the perimeter of a triangle

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

Step2: Simplify the expression
