150 minutes. (15,000/2)=7,500 which is 1/2 of the pool. If it fills 50 gallons per minute you’ll want to divide that by 50;(7,500/50) which equals 150
Answer: Lol, it just says “Invisible”, but ngl it is pretty cool
In B 5^2 = 25. There is no x anywhere.
In C f(x) = 2/x is a function of a reciprocal, not a quadratic.
In D f(x) = 2x^3 + 3x^2 - 5 is a cubic. A cubic is not a quadratic. The highest power of a quadratic is x^2
That leaves A. When you expand the brackets, you get
3(x^2 + 3x- 4x - 12)
2(x^2 - x - 12) when you remove the brackets you get
2x^2 - 2x - 24. The highest power of x is x^2. This is your quadratic.
