Let the number of rows be x
rows = x
seats in each row = x + 20
total seats = 1344
x (x + 20) = 1344
x^2 + 20x - 1344 = 0
(x + 48)(x - 28) = 0
x = -48 (rejected, answer cannot be negative) or x = 28
Therefore,
x = 28
x + 20 = 48
Check:
Row = 28
Numbers of seat per row = 28 + 20 = 48
28 x 48 = 1344 (Correct)
Ans:There are 48 seats per row

Answer:
x = 8
Step-by-step explanation:
A common Pythagorean Triple is a 3-4-5 triangle. The current triangle is 6-x-10. 6 is 2x3 and 10 is 2x5. THus the remaining side must be 2x4 or 8.
You would put 8 where x is and -10 where y is and then you will do -10 to the second power, which you will get 100 and so you will get 104. The answer is
D) 104
