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: 
A theater has n rows of seats.
Therefore the total number of seats in the theater is:

Hence, the correct option is a) n(n-4).
X= -2
25x+30= -22 -x
*subtract 30 from -22*
25x= -52
*divide 25 from each side*
x= -2
