SOLUTION: Find the perimeter of a triangle that has the following sides: 4x + 1, 7x � 2, and 7x +1. Find the expression that represents its perimeter. I have come up with P=(4x+1)+(7x-2

Question 62703: Find the perimeter of a triangle that has the following sides: 4x + 1, 7x � 2, and 7x +1. Find the expression that represents its perimeter.
I have come up with P=(4x+1)+(7x-2)+(7x+1). I am not sure if this one is correct. The solution seemed to come to me too easy. I hope that someone can let me know if the way I set this one up is correct.
