Which did you include in your response?

A
Box 2 will most likely occupy more shelf space.
B
For values of x > 1, the base area of Box 2 is greater.

Explain your reasoning.

Answer:

Box 1’s volume is 3x^5, which is a monomial because it has one term. Box 2’s volume is 4x^5 − x^4, which is a binomial because it has two terms. Box 1 is modeled by a monomial times a monomial, while Box 2 is modeled by a monomial times a binomial.

Which did you include in your response?

A
Box 1’s volume is modeled by a monomial times a monomial, so it will be a monomial.
B
Box 2’s volume is modeled by a monomial times a binomial, so it will be a binomial.

Which did you include in your response?

A
If a box has a greater volume, it can hold more cereal.
B
Box 2 can hold more cereal. Although the value of x is unknown, it represents a length, so it must be greater than zero. For any x > 1, the volume of Box 2 is greater than the volume of Box 1.

Why does this make sense?

A
You use the power of a product law of exponents to combine the exponents; this law says to add the exponents.
B
You use the power of a power law of exponents to combine the exponents; this law says to multiply the exponents.
C
You use the product of powers law of exponents to combine the exponents; this law says to add the exponents.
