Best ResponseYou've already chosen the best response.1Hmmm. So perimeter is all sides added together, can you write an equation for the perimeter of the first one?

Best ResponseYou've already chosen the best response.1Yep but you know the perimeter so go ahead and put that in to x+2y=14 now the second one

Best ResponseYou've already chosen the best response.1Forgot a side 3x+(5/4)y+(5/4)y=21 which simplifies to 3x+(5/2)y=21 so now we have two equations 3x+(5/2)y=21 x+2y=14 any idea how to solve?

Best ResponseYou've already chosen the best response.1You could. Multiply the second equation by 3 and then add the two equations together
