SOLUTION:
Step 1:
In this question, we are given the following:
[tex]-2.\text{ 5( -3 + 4n + 8 )}[/tex]Step 2:
Expanding the expression, we have that:
[tex]\begin{gathered} -2.\text{ 5 ( -3 + 4n + 8 )} \\ \text{solving the bracket first, we have that:} \\ -2.\text{ 5( 4n + 5)} \\ -10n\text{ - 12. 5} \end{gathered}[/tex]
