Step-by-step explanation:
The given expression is
For x=1,
9 is divisible by 3. So, the given statement is true for x=1.
Assumed that the given statement is true for n=k.
This expression is divisible by 3. So,
.... (1)
For x=k+1
Using equation (1), we get
This expression is also divisible by 3.
Therefore the given expression is divisible by 3 for all natural values of x.

Let x represent the time spent for valleyball
Then swimming will be 2x
x + 2x = 4.5
