Question

A triangle has sides with lengths of 5x - 7, 3x - 4, and 2x - 6. What is the perimeter of triangle?

Answer 1

10x -17

Explanation:

The perimeter is the sum of the side lengths:

P = (5x -7) +(3x -4) +(2x -6)

Grouping like terms can make simplification easier:

P = 5x +3x +2x -7 -4 -6

P = 10x -17
