1 x 18 2 x 9 3 x 6 2 x 3 x 3
The factors for 18 are: 1,2,3,6,and 9
GCF(18, 27) = 9so, 18 + 27 = 9*2 + 9*3 = 9*(2 + 3) = 9*5 = 45.
4 x 9, 6 x 6 , 12 x 3, 36 x 1 all make 36.
All the factor strings are 2 x 9 3 x 6 2 x 3 x 3
X/9 = 18 multiply through by 9 X = 162 check 162/9 = 18 18 = 18 checks
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1
|x+9|=18 either x+9=18 or x+9=-18 so x=9 or x=-27 When |a|=b then a=b or a=-b
18 ÷ 9 x 2 = (18 ÷ 9) x 2 = 2 x 2 = 4
9 x 9 = 18 is false do you mean 9x + 9 = 18? then x =1
Well whats x. if x=19, then you do 19-1 ____ 9 19-1=18 18 __ = 18/9= 18 divided by 9 = 2. 9 it all depends on x
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
7/9 x 18 = 147/9 of 18 is 14.
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.

Suppose x is the smaller number then x+9 is the larger. Then x*(x+9)= 162 or x2 + 9x - 162 = 0 or (x-9)*(x+18) = 0 So: x = 9 giving the solution 9 and 18 OR x = -18, giving the solution -18 and -9
(x^18 - 6x^9 + 18)(x^18 + 6x^9 + 18)
