a. The total area of the model is 110 m2. Write an equation to find x. b. Solve the equation by completing the square. (x + 2)(2x + 2) = 110; x = 5.93 m (x + 2)(x + 2) = 110; x = 1.32 m (x + 2)(2x + 2) = 110; x = 3.53 m (x2 + 2)(2x + 2) = 110x; x = 5.93 m

None of those are technically correct. 9.7 x 104 is actually 1,008.8, but if that answer was a choice, it would be that one. if you meant 9.7 times maybe a thousand or more or divided by 10 or more, than the answer choices would be correct, but other than that, they actually arent.
