Answer 1

6(2a -6b +3c) = 12a -36b +18c

 

(3x -2y +9) *4 = 12x -8y +36

 

3(5x -8z -2) = 15x -24z -6

 

-8(7n +9p +1) = -56n -72p -8 

 

3(b -5a) -2(3b +a) = 3b -15a -6b -2a = -17a -3b

 

(4x -7y -7) (-2)= -8x +14y +14

 

-2(3a +1) +(4a -5)= -6a -2 +4a -5 = -2a -7

 

5(2x +3y) - (x-2y) = 10x +15y -x +2y= 9x +17y

Answer 2

12a-36b+18c

12x-8y+36

15x-24z-6

-56n-72p-8t

3b-15a-6b-2a= -3b-17a

-8x+14y+14

-6a-2+4a-5= -2a-7

10x+15y-x+2y= 9x+17y
