distributive property goes like this:
a(b+c)=ab+ac

10.
I'll distribute each seperatly then group

2(x+3)=2(x)+2(3)=2x+6
4(x-2)=4(x)+4(-2)=4x-8

2x+6+4x-8=6x-2



11.
4(3x²-1)=4(3x²)+4(-1)=12x²-4
5(2x+2)=5(2x)+5(2)=10x+10

12x²-4+10x+10=12x²+10x+6



12.
4(2x-8)=4(2x)+4(-8)=8x-32
-(x-4)=-1(x-4)=-1(x)-1(-4)=-x+4

8x-32-x+4=7x-28
