Answers to EXTRA review problems
FIXES FOR THE EXTRA REVIEW
Error on #34 on answer key: the first step should be to add 2 to both sides instead of subtract 2, so it’s (x+2) on the left side of the equation. It turns out that because of squaring later in the problem, the answer on the key is still correct.
Error on #51 on answer key: It should be x = 2.
For all classes: replace your problem #71: It should read: “The sides of a triangle are 9, 12, & 13 inches. The smallest angle has a measure of 42 degrees. Find the measure of the largest angle. Round to the nearest degree.” If you use this problem, then the answer key has the correct solution.
Problem #79: If the last number on your sequence is “2” then you have the most current version of the document. It is then an arithmetic sequence and the next two terms are 3 & 8.
