Note: enter your answer and show all the steps that you use to solve this problem in the space provided. f ( x ) = 9 x 3 + 2 x 2 − 5 x + 4 and g ( x ) = 5 x 3 − 7 x + 4 . what is f ( x ) − g ( x ) ? show all of your steps and write your final answer in factored form.

The answer is 4x³ + 2x² + 2x = 2x(2x² + x + 1)

Step-by-step explanation:

∵ f(x) = 9x³ + 2x² - 5x + 4

∵ g(x) = 5x³ - 7x + 4

∴ f(x) - g(x) = (9x³ + 2x² - 5x + 4) - (5x³ + 0 - 7x + 4)

                 = (9x³ - 5x³) + (2x² - 0) + (-5x + 7x) + (4 - 4)

                 = 4x³ + 2x² + 2x = 2x(2x² + x + 1)

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
