Depends on how big you cut the pieces. If you cut 2x2 inch pieces, a 12x18 cake will yield 54 servings.
its just a line, there are many answers that would work -12x-6y=0 -12x=6y x=-y/2 y=-2x
If you mean: (12x-3)(12x+3) then it is 144x^2 -9
GCF = 12x.24x = 2(12x)36x3 = 3x2(12x)
2*2 - 12x +16 =0 4 - 12x +16 =0 -12x + 16 +4 =0 -12x + 20 =0 -12x = -20 x = 1.666666667
5/4x+7/12x is the same as 15/12x+7/12x = 21/12x
12x-17x = -5
12x - 2x = 10
12x+x = 13x
12x * 4x2 = 48x3
If you mean: 3x^2+12x+12 = 0 then it has two equal solutions of -2

12x-4y+9z+2y =12x-2y+9z
