The Airplane is 280 feet long. Charlie make a scale model of the airplane a t 1:140 of its actual size what is height of the model

What is the binomial expansion of (2x-3)^5

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

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10
