Ireally need with this show work

jay factored the 4 term polynomial x^3 - 9x + 2x^2 - 18 and decided that the complete factorization was (x+2) (x^2 - 9)

before turning in his paper, he checked his final factorization by multiplying out his factors and was sure that he had found the correct factors. when his teacher graded his paper, she marked his answer as incorrect, but gave him one more chance to show the correct factorization.

a) what was jay's mistake?

b) show/describe each step in factoring the 4 term expression correctly and completely:

x^3 - 9x +2x^2 - 18

Two students were asked if they liked to read. is this a good example of a statistical question? why or why not? a yes, this is a good statistical question because a variety of answers are given. b yes, this is a good statistical question because there are not a variety of answers that could be given. c no, this is not a good statistical question because there are not a variety of answers that could be given. no, this is not a good statistical question because there are a variety of answers that could be given

Which description is represented by a discrete graph? kiley bought a platter for $19 and several matching bowls that were $8 each. what is the total cost before tax? the temperature at 9 a.m. was 83° f and is heating up at an average rate of 6°f per hour. what is the temperature x hours later? juan ate an egg with 78 calories and some cereal with 110 calories per serving for breakfast. what is the total amount of calories he consumed? a bottle contained 2,000 ml of liquid and is being poured out at an average rate of 300 ml per second. how much liquid is left in the bottle after x seconds?

Plzzz answer both questions and i will give you 100 points
