(2x+3)(x-1) OuterDirections: Indicate the FOIL for the problem
1 answer:
Answer:
Step-by-step explanation:
This is one of the easier things to do so definitely learn how to do it.
You just start by taking the first number in each parenthesis (F) and then multiply. 2x by x is 3x^2
Then take the outer (O) number from both problems, so the leftmost and rightmost number. 2x times -1 is -2x
Then take the two inner (I) numbers, 3 and x. Multiply and get 3x
Then take the last number in each parentheses (L) which is 3 and -1, get -3

Given that,
Emily reads a storybook the first day,
She reads 1/9 of the whole book, and on the second day, she reads 24 pages.
The ratio of the number of pages read to the remaining pages in the two days is 1:4.
We have to find
How many pages are there in this book?
According to the question,
Let, P is the number of pages,
The first day Emily reads p/9 pages of the whole book,
And the second day she read 24 pages.
The ratio of the number of pages read to the remaining pages in the two days = 1;4 = p/5.
Therefore,
The number of pages reads first day + the number of pages read the second day = The ratio of the number of pages read to the remaining pages in the two days
Hence, there are 270 pages in this book.
