2. If the books are x and y, then xy or yx are the only possible ways.
Unless you allow for one book to the side of the other, one bok on top of the other, one book leaning partially on the other, etc. In that case, there are an infinite number of ways.

Ill skip the factorials and just give you what the calculator does in the end. 8*7*6*5*4*3= 20,160
How many sets of 5 books can be selected from 12 different books?
12!/(5!*7!)The number of ways to arrange nitems is n!, where "!" is the factorial function. The number of ways we can arrange the 12 books is therefore 12!. However, we don't really care what order the first 5 books are in, or what order the last 7 books are in, as long as they're the same books. We therefore divide by the number of ways to arrange 5 books and the number of ways to arrange 7 books.

Suppose that you have an unlimited supply of identical math books history books and physics books All are the same size and you have room on a shelf for 8 books In how many ways can you arrange eight?
Yes. They are real.
How many ways can you arrange seven books on a shelf?

How many ways can you arrange 3 books on one shelf?
Choose 3 then 2 then 1; 3*2*1 = 6 ways.
How many different ways can you arrange 5 out of 7 books on a book shelf?
There are only 5 places on the shelf. You have 7 books to choose from. We will ignore the order of the books on the shelf. The first place can be filled from a choice of 7 books, the next place from 6, the next place from 5, the next from 4, and the last of the 5 places from 3 books. So the number of ways of choosing the 5 is found from 7 * 6 * 5 * 4 * 3 = 2520
How many ways can you arrange 6 out of 8 books on a shelf?
Ill skip the factorials and just give you what the calculator does in the end. 8*7*6*5*4*3= 20,160

Answerthe answer is 24 WHICH is the result of the multiplication: 4x 3 x 2 x 1 = 24. You can try it practically as: Numbering books as A,B, C, and D then the variations are:ABCDABDCBACDBADCCDABCDBADCABDCBABCADBCDACBADCBDAADBCADCBDABCDACBBDACBDCADBACDBCAACBDACDBCABDCADB
There are seven books on the floor the number of books on the shelf is two more than three times the number of books on the floor how many books are on the shelf?
There are seven books on the floor. Let x be the number of books on the floor. The number of books on the shelf is 2 + 3x. From the information given, 3x + 2 = number of books on the shelf. Substitute x=7 into 3x + 2 to find the answer. So, there are 23 books on the shelf.
