True.
To confirm this inequality, we can use a simple algebraic approach.
Given: x > 9
To prove: 2x > 18
We can start by multiplying both sides of the given inequality by 2 (since it is a positive number):
2(x) > 2(9)
This simplifies to:
2x > 18
Since this inequality is equivalent to the one we needed to prove, we can conclude that if x is greater than 9, then 2x is greater than 18.
