3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12
(x2 + 7x - 18) = (x + 9)(x - 2)
x^2 + 18 = 9x x^2 - 9x + 18 = 0 (x )(x ) Since 6 * 3 = 18 and 6 + 3 = 9, (x 3)(x 6) Since the 18 is positive, the factors are either both positive or both negative. Since the 9 is negative, they must both be negative. (x - 3)(x - 6)
3x+12 = 18 3x = 18-12 3x = 6 x = 2

You need to be careful in how you write such questions as it is important to know if you mean: x - 12/2 = 18 or (x-12)/2 = 18 If x - 12/2 = 18 then x = 18 + 12/2 x = 18 + 6 x = 24 If (x-12)/2 = 18 then x - 12 = 18 * 2 x - 12 = 36 x = 36 + 12 x = 48
18 ÷ 9 x 2 = (18 ÷ 9) x 2 = 2 x 2 = 4
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1
2 x 3 x 3 = 18 2 x 2 x 2 x 3 = 24
18 = 9 x 2, so LCM of 18 & 9 is 18. 8 = 2 x 2 x 2; so 18 & 8 share a common factor of 2, so the LCM = 18 x 2 x 2 = 72.
18 = 2 x 3 x 3 36 = 2 x 2 x 3 x 3 GCF = 2 x 3 x 3 = 18
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
18 x 1/2 = 18/2, or 9
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
2 x 3 x 3 = 18 2 x 2 x 2 x 3 = 24
If you want to stick to integers: 1 x 18 = 18 2 x 9 = 18 3 x 6 = 18 -1 x -18 = 18 -2 x -9 = 18 -3 x -6 = 18
18 x 32 x 2 x 2 = 2,304
