Given

[tex](4n-2)(7-n)[/tex]

To evaluate this expression for n=5, the first step is to replace it with the given value for n.

[tex](4\cdot5-2)(7-5)[/tex]

Then you have to solve the operations inside both parentheses:

[tex]\begin{gathered} (20-2)(2) \\ (18)(2) \end{gathered}[/tex]

Once solved the operation inside the parentheses terms, you can multiply the results

[tex]18\cdot2=36[/tex]

This means that (4n-2)(7-n) equals 36 when n=5
