Answer:
The correct option is a) n(n-4).
Step-by-step explanation:
Consider the provided information.
Let n represents the number of rows.
The number of seats in each row is 4 less than the number of rows.
This can be written as: [tex]n-4[/tex]
A theater has n rows of seats.
Therefore the total number of seats in the theater is:
[tex]n(n-4)[/tex]
Hence, the correct option is a) n(n-4).
