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.

Yes, you got it right. Now combine the x's and the numbers to simplify your answer.
P=%284x%2B1%29%2B%287x-2%29%2B%287x%2B1%29+=+18x.

P=(4X+1)+(7X-2)+(7X+1)
P=4X+1+7X-2+7X+1
P=18X
