Question

What is the perimeter of the triangle with sides ( 8x + 2) , (5x - 4) and (9x + 3)? Show all supporting work and your final answer. Explain the steps you used to find your answer.

Answer 1

Answer: The perimeter should be 22x + 1

Step-by-step explanation:

-In order to find the perimeter, you have to combine like terms:

$( 8x+2), (5x-4), (9x+3)$

-You first add up the integers that have the variable $x$ :

$8x+5x+9x=22x$

-Then, you add up the integers that don't have the variable $x$ :

$2-4+3=1$

-Result:

$22x+1$
