1. A rectangle has a length of 4x 2 y 4 units and a width of 5x 2 y units. What is the area of the rectangle? A 20x 4 y 4 B 20x 4 y 5 C 9x 4 y 5 D 9y 3 Area of a rectangle is found by the formula A = lw. If you are looking for the area, multiply length and width. If you are looking for the length, divide the area by the width. Exponent Rules: Multiply Coefficients, Add Exponents Exponent Rules: Divide Coefficients, Subtract Exponents We are multiplying! Correct Answer! Do not forget the understood exponent of 1 Multiply Coefficients, not add! 1 This is called an understood one CONTINUE CLICKING SCREEN FOR HELP AND HINTS

2.At a sandwich shop, customers can order 1 type of meat, 1 type of cheese, and 1 type of bread. Meat: Turkey, Ham, Roast Beef Cheese: Cheddar, Provolone Bread: White, Wheat, Rye, Sourdough What is the probability of choosing a turkey and provolone on rye? CONTINUE CLICKING SCREEN FOR HELP AND HINTS Correct Answer! F 1/3 G 1/12 H 1/9 J 1/24 Consider the total number of choices Not sure where the 12 came from?? Multiply your number of choices, not add Probability requires a want/total Find the “total” number of sandwich choices by multiplying the number of selections: 3 x 2 x 4 = 24 (3) (2) (4) Now find the “want” by multiplying your choices: 1 x 1 x 1 = 1 (1) 24 1

3.Which of the following nets forms a square pyramid? ABC A net is a 2-D (folded out) view of a 3-D object Correct Answer!This is a triangular prism.This is a triangular pyramid. A square pyramid has a base of a square and folds up to a single point. CONTINUE CLICKING SCREEN FOR HELP AND HINTS

4. What is the solution set for the equation: 8x 2 – 16x – 24 = 0 F {1, 3} G {1, -3} H {-1, 3} J {-1, -3} Correct Answer! Watch signs! If you would like, you can factor out an 8 and create a simpler equation to work with: 8x 2 – 16x – 24 = 0 x 2 – 2x – 3 = 0 You may solve by factoring, quadratic formula, completing the square or graphing. The easiest way is to graph and find the x-intercepts! Just pretend it says “= y” instead of “= 0” 3 CONTINUE CLICKING SCREEN FOR HELP AND HINTS

5. The table below shows various values of f(x) for given values of x. Which equation best represents the situation? A f(x) = 3x + 2 B f(x) = x + 2 C f(x) = 3x D f(x) = 2x Correct Answer! Table does not match x0123 f(x)25811 Anytime you see “f(x) =“ or “y =“ use your calculator. Type in your equations and then check your table. To get to the table screen, type 2 nd Graph.
