You will need: 12*24 = 288 square feet
If you mean: (12x-3)(12x+3) then it is 144x^2 -9
GCF = 12x.24x = 2(12x)36x3 = 3x2(12x)
Well, first of all you need to unlock it. After that, you equip it onto a sniper rifle and when you zoom in, it will be the 12x scope.
100 of them.
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
You need to rivse your question. It appears that there is not an equation here. 4*2+12x+9? You can't really solve this it is more of a statement. You can however simplify it to 12x+17- Whoever wrote this obviously can't read. It's supposed to be 4x^2+12x+9 (2x+3)(2x+3)
81
12x - 2x = 10
12x+x = 13x
