Question

Multiply the following:
3ab×4c
(3x+2y)×5xy
(2a+3b-4c)×12
(8x-2y)×(3x+5y)
(7a+8)×(2a+3)
(6a+7b)×(12+3b)
(X×X+5)×(y+7)

Answer 1

Step-by-step explanation:

3ab×4c=12abc

(3x+2y)×5xy=15x+10y

(2a+3b-4c)×12=24a+36b-48c

(8x-2y)×(3x+5y)=24x²-10y²

(7a+8)×(2a+3)=14a²+24

(6a+7b)×(12+3b)=12+6a+24b²

(X×X+5)×(y+7)=12+x²+y
