Factor the following trinomial: 2x² - 4x - 5

• A. (2x + 1)(x + 5)

• B. (2x - 5)(x + 1)

• (2x+1)(x-5)

• Not factorable/ Prime

A drummer and a guitarist each wrote songs for their band. The guitarist wrote 8 fewer than twice the number of songs that the drummer wrote. They wrote a total of 46 songs. Which system of equations models this situation if the drummer wrote d songs and the guitarist wrote g songs?

• F. g = 2d - 8

  g + d = 46

• G. g = 8 - 2d

  g = 46 - d

• H. d = 2g - 8

  d = 46 - g

• J. d = 8 - 2g

  d + g = 46

A sports magazine prints 12 issues per year, and a technology magazine prints 10 issues per year. The total number of pages in all the issues of the sports magazine for one year is 32 more than the total number of pages in all the issues of the technology magazine for one year. Each issue of the sports magazine has 18 fewer pages than each issue of the technology magazine. Which system of equations can be used to find s, the number of pages in each issue of the sports magazine, and t, the number of pages in each issue of the technology magazine?

• s = t - 18

  12s = 10t + 32

• t = s - 18

  10t = 12s + 32

• s = t - 18

  10s = 12t + 32

• t = s - 18

  12t = 10s + 32
