Simplify the expression: 2( x^3 - 3x^2 + 5x - 7 ) A. 2x^3 + 6x^2 + 10x + 14

B. 2x^3 - 6x^2 + 10x + 14

C. 2x^3 + 6x^2 + 10x - 14

D. 2x^3 + 6x^2 + 10x - 14

=2x^3−6x^2+10x−14

i dont know what choice that is but thats the correct answer

Step-by-step explanation:

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.
