Answer: the number of seats in the 10th row is 36 seats and the number of total seats in cinema is 66 seats because there is 25 rows and the first row started out at 18 seats
Step-by-step explanation:
Answer:73 and remainder of 3
Step-by-step explanation:
295/4=73 and a remiander of 3
Xy 14
x + y = -4
x + y = -4
x - x + y = -x - 4
y = -x - 4
xy = 14
x(-x - 4) = 14
x(-x) - x(4) = 14
-x² - 4x = 14
-x² - 4x - 14 = 0
-1(x²) - 1(4x) - 1(14) = 0
-1(x² + 4x + 14) = 0
-1 -1
x² + 4x + 14 = 0
x = -(4) ± √((4)² - 4(1)(14))
2(1)
x = -4 ± √(16 - 56)
2
x = -4 ± √(-40)
2
x = -4 ± 2i√(10)
2
x = -2 ± i√(10)
x + y = -4
-2 ± i√(10) + y = -4
- (-2 ± i√(10)) - (-2 ± i√(10))
y = -2 ± i√(10)
(x, y) = (-2 ± √(10), -2 ± √(10))
The two numbers that multiply to 14 and add up to -4 are -2 ± i√(10).
Answer:
4
x - ----- = 3
y
Step-by-step explanation:
I'm assuming that you mean:
4
x - ----- + 2 = 5
y
Subtracting 2 from both sides, we get
4
x - ----- = 3
y
adding 4/y to both sides yields:
4
x = 3 + -----
y
