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
The answer to your question is 7
Answer:
Width <= 12
Width >= 6
Step-by-step explanation:
36 <= 2(12) + 2x <= 48
36 <= 24 + 2x
36 - 24 <= 2x
12/2 <= x
x >= 6
24 + 2x <= 48
2x <= 48 - 24
x <= 24/2
x <= 12
Answer:
x = 36
Step-by-step explanation:
Assuming that line EAF + FAB = 180, we can substitute the lines with their x values to become 3x + 2x = 180 = 5x
Then x = 180/5 = 36
