Question

(There is a picture but I can't put it in the question)

Sides of the triangle: 2x, 4x-2, 3x-1


Find a single expression that represents the perimeter of the triangle.
A) x + 1
B) 5x − 3
C) 3x − 1
D) 9x − 3

Answer 1

D.

Explanation:

The perimeter = the sum of the 3 sides.

Perimeter = 2x + 4x - 2+ 3x - 1

= 9x - 3.

Answer 2

The perimeter of a triangle is just adding all the sides.

So, (2x)+(4x-2)+(3x-1)= 9x-3

So, the answer is D, 9x-3
