A,(x-4)^2-48=-12
b,(x+3)^2:3-1=-10
c,2.x-3.x+18=x
d.-2.(x+7)+3.(x-2)=-2

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
