Question

A tower has a triangular base with side lengths 6y ft, 7y + 2 ft, and 5x – 7 ft. Write a simplified expression for its perimeter.

Answer 1

6y+7y+2+5x-7
11y+5x-5

Answer 2

6y + 7y + 2 + 5x - 7
Collect like terms such as the "y" terms and constant terms like 2 and - 7

6y + 7y = 13y

2 - 7 = -5

5x cannot add with another term so final answer is
13y + 5x -5

Answer 3

Wait...Eliza how did you get 11y? 6y + 7y = 13 y..?

Answer 4

oh woops... :) i can't add....
