The length of each of the two congruent sides of an isosceles triangle is 3x - 1. The length of the third side is 2x + 1. The perimeter is 55 feet. Which equation does NOT represent the perimeter?

8x - 1 = 55

6x - 2 + 2x + 1 = 55

2 (3x - 1 + 2x + 1) = 55

2 (3x - 1) + (2x + 1) = 55

Answer 1

Answer: The third choice

Step-by-step explanation:

This equation does not represent the perimeter.

To write the equation:

2(3x - 1) + (2x + 1) = 55
6x - 2 + 2x + 1 = 55
8x - 1 = 55

Thus, 3 of the choice represent but the the third choice didn’t appear in the equation.
