9c⁹·2c⁵ write the product in its simplest form

Step-by-step explanation:

Multiply the numbers as usual.

However, note the variables. They both are the variable c, so you can multiply the variables together. To solve, add the exponents attached to the variable:

9 * 2 = 18

* = =

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
