Algebra II First Semester Assignment #5 (Review of Sections 1.1 through 1.8) Do not rely solely on this review to prepare for the test. These problems are meant only as a means to remind you of the types of problems we have discussed and the topics we have covered. To fully prepare for the test you need to take notes in class, be well-organized, do all your homework, ask questions when needed, and study from notes, homework assignments, and quizzes as well. You will not be allowed to use a calculator on the first test of the year. Simplify each expression. 1. 5 5 + 7( 3) + 4. 35 3(6 ) 3 3. 3 [5 + ( 4) 4 ] 15 1 S 1 A s s i g n m e n t # 5
