1. I have a box with the following dimensions:

2. length = (13-2x)

3. width = (10-2x)

4. height = x

Which equation expresses the volume of the box (in terms of x) correctly?

• V(x) = (13–2x)(10–2x)(10-2x)

• V(x) = (13–2x)(10–2x)(x)

• V(x) = (10–2x)(x)

• V(x) = L x W x H

Which of these are examples of a polynomial? [Multiple correct answers!]

• f(x) = x² + 4x - 5

• g(x)

• p(x) = z⁴ - y⁵

• h(t) = t⁵ + t⁴ - 6t + 15

1. If I have a rectangle with sides of length = 5x and width (150-x²), which equation defines the area of my rectangle?

• A(x) = (5x)(5x)

• A(x) = (5x)(150-x²)(x)

• A(x) = (150-x²)(5x)

• A(x) = (150-x²)

1. I put in $400 to a savings account with yearly interest rate (growth factor) “x”. I added another $300 one year later.

2. What equation defines the total amount 6 years after I deposited the original $400?

• f(x) = 400x⁶ + 300x⁶

• f(x) = 400x⁶ + 300x⁵

• f(x) = 400x⁶ + 300x⁴

• f(x) = 700x⁶

Here is an equation A(x) for the interest accumulated on a savings account:

A(x) = 500x⁴ + 350x³ + 400x

If I add another $100, what is the function B(x) after one more year in the account?

• B(x) = 500x⁵ + 350x⁴ + 400x² + 100

• B(x) = 500x⁶ + 350x⁴ + 100x

• B(x) = 500x⁴ + 350x³ + 400x + 100

• B(x) = 500x⁵ + 350x⁴ + 400x² + 100x
