When we consider Statement 2, why can't x^2 = 18? It just says that it's divisible by 9. So x would not come out to be a number that is divisible by 3. In that case, statement 2 would be insufficient. I ended up picking A as the right choice. Please help!
If x^2 = 18, then x is not an integer (x would equal 3√2, which is roughly 4.24), but the question tells us x is an integer, so x^2 cannot equal 18.
