There is not enough information here to answer this question accurately. The limitations of this website leave us unable to see exponents or operational signs. You might be asking us to factor x3 + 18 or you might be asking for information on the X318, a futuristic jet that you read about somewhere. In the future, it would help us if you write the terms out (plus, minus, to the power of, etc.)
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
We have, f(x) = x2-3x-18 f(x) = x2-3x-18 = x2-6x+3x-18 = x(x-6)+3(x-6) = (x+3)(x-6) Factors are (x-6) and (x+3).
No. 9 is a composite number (3 x 3). But it is a factor of 18. Factors of 18 are 1, 2, 3, 6, 9, 18. 18 = 2 x 3 x 3
2 x 3 x 3 = 18
-18+x = 3 x = 3+18 x = 21
the fact family of the numbers 3, 6, and 18 is: 3 x 6 = 18; 6 x 3 = 18; 18 ÷ 3 = 6; 18 ÷ 6 = 3
18 = 2 x 3 x 3 36 = 2 x 2 x 3 x 3 GCF = 2 x 3 x 3 = 18
If you mean -x +x/3 = 12 then the value of x is -18 Check: --18 +(-18/3) = 12
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
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 3 x 3 x 5 = 45
1 x 18 2 x 9 3 x 6 2 x 3 x 3
2 x 3 x 3 = 18 2 x 2 x 2 x 3 = 24
18 = 1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
31/3 of 18 = 31/3 x 18 = 3x3+1/3 x 18/1 = 10/3 x 18/1 = 10x18/3x1 = 180/3 = 60
18 = 2 x 3 x 3
