Question

Can someone check my answers?

24. A box has a volume given by the trinomial x^3+3x^2–18x. What are the possible dimensions of the box? Use factoring.

x – 3, –x – 3, and –x – 6
x, x + 3, and x – 6******
x, x – 3, and x + 6
x – 6, x – 6, and x + 6

25. A refrigerator has a volume given by the trinomial y^3+y^2–56y. What are the possible dimensions of the refrigerator? Use factoring.

y, y + 8, and y – 7*******
y, y – 8, and y + 7
y + 7, y + 7, and y – 7
y + 8, –y + 8, and –y + 7

Answer 1

Using your answer for 24, I come up with a volume of x^3 - 3x^2 - 18x, which is not what they are wanting.
