Jack read 1/6 of a book on monday and another 1/3 of it on tuesday. he took another 4 days to finish reading the book. he read the same number of pages on each of the four days. a) what fraction of the book did he read each day? b) if he read 40 pages on each of the four days, find the number of pages in the book.

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
