Ok this is how it work:
1+4=5
2+5=12=2+1+4+5=12
3+6=21=12+3+6=21
8+11=? do the same to that take 21+8+11=40
ask me if you don't get it. I explain it further.

Answer:
30 seats
Step-by-step explanation:
To answer this question, we will be assigning values for both rows and seats.
R = Rows
S = Seats
Remember that rs = 600
r = s - 10, plug this equation into rs = 600, and factor it:
s(s-10) = 600
s^2-10s-600 = 0
(x-30)(x+20) = 0
There are 30 seats in the row. To determine which one is your answer, your answer MUST be positive because it is impossible to have negative seats. (x-30) is 30, which is the positive value found when factoring.
