The Solution:
Given the expression below:
We are required to write the answer in the form below:
[tex]Q+\frac{R}{D}[/tex]
This means that:
[tex]\frac{t^2+11t+18}{t+9}=t+2[/tex]
So, writing the answer in the required form, we have:
[tex]\begin{gathered} Q+\frac{R}{D}=(t+2)+\frac{0}{t+9}=t+2 \\ \text{this means that:} \\ Q=t+2 \\ R=0 \\ D=t+9 \end{gathered}[/tex]
Therefore, the correct answer is:
[tex]t+2[/tex]
