Aiden borrows a book from a public library. he read a few pages on day one. on day two he reads twice the number of pages than he read on day one. on the third day, he reads six pages less than what he read on the first day. if he reads the entire book that contains 458 pages. write how many pages he read on day three

Step-by-step explanation:

On day one = few pages (x)

On day two = twice of pages read on day one (2x)

On day three= 6 less than the page read the first day (x-6)

Total pages read = x+2x+(x-6)=458

4x-6=458

4x=458+6=464

x= 464÷4

x=116

Pages read on day three was 110

step-by-step explanation:

which of the following statements correctly describes the expression below based on its degree and number of terms?

314 - 7x2 + 11

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
