Let x be the number of rotations left to run, then
x + 6 ≥ 45
The answer would be 202 inches
X^2+7x-18=0
x^2+9x-2x-18=0 ( splitting middle term)
x(X+9)-2(x+9)=0
(x-2) * (X+9) =0
Therefore, X=+2 or -9
Let's say n = the unknown number
then, 3n-25 would be your answer
9514 1404 393
Answer:
18
Step-by-step explanation:
Only 1 and 2 will have single-digit cubes. Only 1^3 will still be a single digit after 7 is added. The tens digit must be 1, and the units digit must be 1+7=8.
The number is 18.
