We need the remember that:
Therefore, the radicand (In this case ) must be a perfect cube in order to get a whole number.
Remember that a perfect cube are the numbers that have exact cube roots. Therefore, "y" must be a factor of 144.
Now, we need to descompose 144 into its prime factors:
Then, the factors of 144 are:

8 is a constant.
This expression is the sum of three terms.
Answers
Answer:
The correct statements are:
6 is a coefficient.The expression has two variable terms.8 is a constant.This expression is the sum of three terms.Explanation:
The coefficient is the numerical factor that is multiplied by a variable term. In this case, 6 is a coefficient that is associated with a constant term.Variable terms have a variable factor. In this case, the expression has two variable terms (8y^2 and 3y).A constant is a term that has no variable factor. In this case, 8 is a constant term.The expression has three terms: 8y^2, 3y, and 6. The term 8y^2 is a variable term, the term 3y is a variable term, and the term 6 is a constant term.Learn more about Algebraic Equations here:

Are the ratios
25/45
and
15/27
proportional? Explain.
Answers
Answer:
Yes
Step-by-step explanation:
First ration we will divide by 5 (both numbers) and second one by 3 (again both numbers).
First ratio becomes (25:5)/(45:5) = 5/9
Second ratio becomes (15:3)/(27:3) = 5/9
Since we can simplify them in that way that both are the same that means they are proportional.
because when we make them smaller like 25/45 divide by 5 and 15/27 divide by 3 it forms 5/9
Answer:
Yes
Step-by-step explanation:
If you divide 25/45 by 5 you get 5/9
Then you divide 15/27 by 3 you also get 5/9
Since both are equal to 5/9 they are proportional.

b. How many cubic feet of water are in the pool? (3 points)
Volume: __________ ft3
c. If one cubic foot contains about 7.5 gallons, how many gallons of water are in
the pool? (3 points)
Water: __________ gallons
Answers
Answer:
a. Length = 25 yds. × 3 ft./yd. = 75 ft.
Width = 8 × 3 yds. × 3 ft./yd. = 72 ft.
b. Volume = 75 ft. × 72 ft. × 6 ft.

The original problem is solved by multiplying 32*8*31, which gets you to 7,936.
I rounded these numbers up and down to get a simpler equation of 30*10*30 which is exactly 9,000.
32 • 8 = 256
Then, you’re going to take the result and multiply it by the amount of days (31):
256 • 31 = 7,936
The closest number to 7,936 (from the given answers) would be 9,000.
Your answer would then be C.
