Can someone please help me out with this question? ​

Answer 1

B and B

Explanation:

For the first problem, the range is simply the data set rearranged from smallest to largest.

For the second problem, you just have to cross multiply each variable in order to expand the equation and get an answer.

The answer for that one is
`12x^(3) -42x^(2) +8x+55`
