Answer 1

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: $n-4$

A theater has n rows of seats.

Therefore the total number of seats in the theater is:

$n(n-4)$

Hence, the correct option is a) n(n-4).
