Question

What is the perimeter of the triangle expressed as a polynominal?

A) -9x + 6
B) 8x - 6
C) 9x - 8
D) 9x - 8

Answer 1

To find the perimeter you would add up all of the sides, so:
5x - 2 + 3x + 4 + x - 10
Now you combine the like terms
5x + 3x + x = 9x
-2 + 4 - 10 = -8
So your final answer is C) 9x - 8. I hope this helps!
