Explanation:
Here we have the following expression:
[tex]\frac{n}{6}+2 \\ \\ \\ When: \\ \\ n=12[/tex]
What we need to do is to substitute [tex]n=12[/tex] into our expression. Therefore:
[tex]\frac{n}{6}+2 \\ \\ \frac{n}{6}+2 =\frac{12}{6}+2 =2+2=4[/tex]
Finally, when evaluating [tex]n=12[/tex] into the expression the result is 4.
