The total area of the model is 110 m^2. write an equation to find x. b. solve the equation by completing the square. 1- (x + 2)(2x + 2) = 110; x = 3.53 m 2- (x + 2)(x + 2) = 110; x = 1.32 m 3- (x2 + 2)(2x + 2) = 110x; x = 5.93 m 4- (x + 2)(2x + 2) = 110; x = 5.93 m

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
