A rectangular auditorium seats 2184 people. The number of seats in each row exceeds the number of rows by 17. Find the number of seats in each row.
lemme see
129 - 17 =112 rows
seats = 129 * 112 = 14448 hmmm
lemmme try
r = s - 17
s r = 2184
s (s-17) = 2184
s^2 -17 s -2184 =0
s = [ 17 +/- sqrt (289 + 8736) ] / 2
= [ 17 + 95 ] / 2
= 56
