Question 1186251
the santa rosa sport complex contain 504 seats. 
there are 3 fewer rows than there are seats per row.
find the number of rows and seats per row
:
let s = the no. of seats per row
"there are 3 fewer rows than there are seats per row.", therefore:
(s-3) = no. of rows
:
s(s-3) = 504
a quadratic equation
s^2 - 3s - 504 = 0
YOu can use the quadratic formula; a=1; b=-3; c=-504, but this will factor to
(s-24)(s+21) = 0
the positive solution
s = 24 seats and obviously 21 rows
:
:
Check 24 * 21 = 504
