8n ≥425-175
8n ≥250
n ≥250/8
n ≥31.25
They would need to sell at least 32 bottles to raise more or equal to $425.
32•8=256
256+175=$431
431 ≥425
Here you go. Answer is in the Image.

Thank you I hope u have an amazing day
Step-by-step explanation:
(x - 2)⁴
(x - 2)²(x - 2)²
(x - 2)(x - 2)(x - 2)(x - 2)
(x(x) - x(2) - 2(x) + 2(2))(x(x) - x(2) - 2(x) + 2(2))
(x² - 2x - 2x + 4)(x² - 2x - 2x + 4)
(x² - 4x + 4)(x² - 4x + 4)
x²(x² - 4x + 4) - 4x(x² - 4x + 4) + 4(x² - 4x + 4)
x²(x²) - x²(4x) + x²(4) - 4x(x²) + 4x(4x) - 4x(4) + 4(x²) - 4(4x) + 4(4)
x⁴ - 4x³ + 4x² - 4x³ + 16x² - 16x + 4x² - 16x + 16
x⁴ - 4x³ - 4x³ + 4x² + 16x² + 4x² - 16x - 16x + 16
x⁴ + 8x³ + 24x² - 32x + 16
The constant term in the expansion of the binomial is 16.
You can find the mean of negative numbers just the same as for positive numbers. It doesn't hurt for the mean to be negative.
For example, with the number -9, -5, -4, -3, -1 you can find the mean jsut as any other numbers
-9+-5+-4+-3+-1=-22
-22/5=-4.4
the mean for those set of numbers is -4.4
