Chapter 1 Review Answers

NOTATION TIPS:
- I have written "squared" as ^2
- ( ) around part of a fraction just means that whole quantity is in the numerator or denominator--you don't need ( ) in your answer
- I have written "less than/greater than or equal to" as <= and >=

REMEMBER: We will not take time to discuss the review in class on the day of the test, so be sure your questions are answered before then! I will be available on Thursday in the morning and after 3:00, after school on Friday, and on Monday morning at 7:15.
