Factor by grouping.
72x^3 - 56x^2 + 45x - 35

Step-by-step explanation:

Out of 72x^3 and 56x^2 you can factor 8x^2

Out of 45x and -35 you can factor 5

So if you put those together you get 8x^2+5

8x^2*9x=72x^3 and 8x^2*-7= -56x^2

5*9x=45x and 5*-7= -35

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.
