Which of the following is the smallest prime number greater than 200? A. 201. B. 205. C. 211. D. 214. A prime number is a number larger than 1 that has only itself and 1 as factors. (It can be e... venly divided only by itself and by 1.) 201 is divisible by 3; 205 is divisible by 5; 211, however, is a prime number If 40% is equal to the fraction x/30, what is the value of x? A. 0.4 B. 15 C. 1,200 D. 12 Change 40% to a decimal and write an equation to solve for x. 0.4 = x/30. Multiply both sides by 30. You are "undoing" the division. The expression "5 factorial" equals A. 125. B. 120. C. 25. D. 10. The product of all integers from 1 to x is called the x factorial. The product of all numbers from 1 to 5 is 5 factorials. Thus (5)(4)(3)(2)(1) = 20 (3)(2)(1) = 60 (2)(1) = 120 (1) = 120. The expression 5 factorial" is equal to 120 What is the result of subtracting 3x² - 5x - 1 from 8x² + 2x - 9? A. 5x² - 3x - 10 B. -5x² - 3x - 10 C. 5x² +7x - 8 D. -5x² - 7x + 8 To subtract one polynomial from another, you change the signs of the terms in the subtrahend. First write the example as a subtraction in arithmetic. (From) 8x² + 2x - 9 (Take) – (3x² - 5x – 1) Then change the signs of the terms in the bottom row (the subtrahend) and combine terms that are alike. 8x² + 2x - 9 -3x² + 5x + 1 ___________ 5x² + 7x - 8 [Show More]
