Question 41567: A triangle has sides 2x - 5, 3x + 1 and 4x + 2. Find the polynomial that represents its perimeter.
Is it
9x - 2
Thanks for help Answer by mszlmb(115) (Show Source):
You can put this solution on YOUR website! Perimeter's all the sides added up so we have
(2x - 5)+(3x + 1)+(4x + 2) which we can safely convert to
2x-5+3x+1+4x+2 change the order around a little..
2x+3x+4x-5+1+2 solve
9x-2
yup, you got it right
