Answer:
18+7=25
Step-by-step explanation:
R * s = 273
r = s - 8.....s = r + 8
r(r + 8) = 273
r^2 + 8r = 273
r^2 + 8r - 273 = 0
(r - 13)(r + 21) = 0
r - 13 = 0
r = 13
r + 21 = 0
r = -21.....extraneous solution...not ur answer
r = 13
s = r + 8 = 13 + 8 = 21
so there are 13 rows.....each row containing 21 seats
