Which equation describes multiplication using this area model? 85×7=(80+5)×7=80×7+5×7

87×5=(80+7)×5=80×5+7×5

80×75=(7+5)×80=7×80+5×80

80×57=(5+7)×80=5×80+7×80
A rectangle. A vertical line divides the rectangle into two smaller rectangles. To the left of the rectangle is the number 5. Above the first small rectangle is the number 80. Above the second small rectangle is the number 7.

#1-20 state whether the angles are alternate interior, alternate exterior, vertical, or corresponding angles.

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
