The correct option is 1.
Step-by-step explanation:
The difference of cubes is defined as
The given expression is
It can be written as
Using the property of exponent, the above expression can be written as
![[\because (x^m)^n=x^{mn}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28x%5Em%29%5En%3Dx%5E%7Bmn%7D%5D)
This is a difference of cubes.
Therefore the correct option is 1.

Answer: 1 cup of sugar; 2 and 1/4 cups of flour; and 1 and 1/2 cups of milk
Step-by-step explanation:
Or simplified; 1 cup of sugar; 9/4 cups of flour; and 3/2 cups of milk
explanation: (do everything times 3)
A. 7 hours ago the temperature was 7 * 1,5 = 10,5 degrees more, so if now it's 0, then it was 10,5 degrees 7 hours ago.
b. in six hours it will be 6 * 1,5 = 9 degrees less, so if it's 0 now, then it will be -9 degrees in 6 hours.
c. the temperature was reading 6 degrees 4 hours ago because:
x * 1.5 = 6 / ÷1.5 (both sides)
x = 4
d. -8 is expected to be in 5 hours and 15 minutes because:
x * 1.5 = 8 / ÷1.5 (both sides)
x = 5 1/3
