Answer to the Polynomial Division: 
At the time the cannonball reaches the ground, the vertical height of the cannonball from the ground is 0, i.e. h = 0.
Thus, the time it will take the cannonball to reach the ground is given by

Therefore, it will take the cannonball 8 seconds to reach the ground.

Answer:
<h2>Multiplication.</h2>
Step-by-step explanation:
The given expression is

For
, we have

Notice that the first operation we need to do is multiplication, because that's the right order of operations when we solve these kind of expressions.

Then, we subtract

Now, we divide

Finally, we sum

Therefore, the right answer is multiplication.
