What is the perimeter of the triangle expressed as a polynomial? 2x-3                    x-12  7x+1 a. -10x + 14 b. 9x- 14 c. 10x +14 d. 10x - 14

If the triangle's sides are given by

2x-3                  

 x-12

 7x+1

Then all you have to do is to add them up, simplify your result and compare your result to each of:

a. -10x + 14
b. 9x- 14
c. 10x +14
d. 10x - 14

Adding together the following, we get:

 2x-3                  
  x-12
 7x+1

10x -14
