There will also be a test over this material the first week of school. It will be your first test grade. You must show all work on a separate sheet of notebook paper. Students are epected to know from memory all other relevant formulas, including: - Sum of the angles in a triangle - Pythagorean Theorem - Area and perimeter of triangles, rectangles, and squares - All formulas for linear equations (slope formula, slope-intercept and point-slope forms) In order to be prepared for the beginning eam, students should be able to do all of the following problems and related problems as well. The answers are provided for you to check your work. Show work where necessary. Practice problems. Translate to an algebraic epression: seven less than twice a number.
