Which operation between two polynomials will not always result in a polynomial? A. Addition B. Subtraction C. Multiplication D. Division 2. What is the product of the expression (3?? + 6)2? A. 6??2 + 12 B. 9??2 + 36 C. 9??2 + 18?? + 36 D. 9??2 + 36?? + 36 3. Find the difference of the two polynomials: (2t3 + 3t – 4) – (4t2 – 6t). 4. Which is the simplified form of this expression? (2x + 3) (x – 6) – 2x2 + 3x + 30 A. 4x2 – 6x + 12 B. -2x2 + 6x + 27 C. -6x – 12 D. -6x + 12 5. In the diagram at the right, the length of a square is (3x + 7) units. The dimensions of the cut-out rectangle are x by (2x + 5) units. Which choice expresses the area of the shaded regions, in square units? (*Complexity Level 3) A. 7x2 + 37x + 49 B. 11x2 + 47x + 49 C. 7x2 + 47x + 49 D. 7x2 + 5x + 49 2MAFS.912.A-CED.1.1 (calculator neutral) - Content Complexity Level 2 *Also assess MAFS.912.A-REI.2.3 and MAFS.912.A-CED.1.4 Create equations and inequalities in one variable and use them to solve problems. Include equations arising from linear and quadratic functions, and simple rational, absolute, and exponential functions. 1. You have money in your wallet, but you don’t know the exact amount. When a friend asks you, you say that you have 50 dollars give or take 15. Which equation below represents how you could find the smallest and largest amount of money in your wallet? Let h represent the exact amount in your wallet. A. | h – 35 | = 15 B. | h – 15 | = 50 C. | h – 50| = 15 D. | h – 15| = 35 2. John’s phone company offers 2 cell phone plans, A and B. Both plans offer 450 free minutes per month, but plan A charges $40 per month and $0.35 for each additional minute, while plan B charges $45 per month and $0.30 for each additional minute. Which inequality shows the number of minutes, x, that John may use in a month in order to make plan B the better plan for that month? A. 40 + 0.35(x – 450) < 45 + 0.30(x – 450) B. 40 + 0.35x < 45 + 0.30x C. 40 + 0.35(x – 450) > 45 + 0.30(x – 450) D. 40 + 0.35x > 45 + 0.30x 3. At a yearly basketball tournament, 64 different teams compete. After each round of the tournament, half of the teams remain, as shown in the accompanying table. Which equation models the relationship between the round and the number of teams remaining? [Show More]
