Find the product of
(3y2 + 2y + 2)(3y2 – 4y – 5)

= 9y^4 -6y^3 -17y^2 -18y -10

Step-by-step explanation:

(3y^2 + 2y + 2) x (3y^2 – 4y – 5)

9y^4 - 12y^3 - 15y^2 + 6y^3 -8y^2 -10y +6y^2 -8y -10

= 9y^4 -6y^3 -17y^2 -18y -10

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:

24
