Short Answer

Your teacher will grade your responses to to questions 20–25 to ensure you receive proper credit
for your answers.

Show your work or the intermediate steps for full credit.

When submitting an answer in the form of an exponent, use a caret (^) to indicate the power. For
example, 53 would be written as 5^3.
When submitting an answer in the form of a fraction, use a forward slash (/) to separate the
numerator and denominator. For example, one-half would be written as 1/2.
