Best ResponseYou've already chosen the best response.0I think you're right, but you have them expressed as a combination of multiplication and addition. I assume ones side is 3x2, and the other dimension is 5x+7. The perimeter would be expressed as P=2(3x2) + 2(5x+7) P=6x4 + 10x+14)=16x +10

Best ResponseYou've already chosen the best response.0If I followed the way you expressed it, it would be\[(9x ^{2}12x+4)+(25x ^{2}+70x +49)\] A totally different looking animal.
