Answer:
40,320.
Step-by-step explanation:
We are asked to find the number of ways in which 8 books could be arranged on a shelf.
The 1st could be arranged in 8 ways. Since one place is filled, so 2nd book could be arranged in 7 ways.
Similarly, the 3rd book could be arranged in 6 ways as first two places are already taken. This process will go on.
So the 8 books can be arranged in
Therefore, 8 books could be arranged in 40,320 ways.
Answer:
x = 4
Step-by-step explanation:
From the pythagoras theorem
(x+2)^2 = x(5+x)
x^2 + 4x + 4 = 5x + x^2
x^2 + 4x + 4 - 5x - x^2 = 0
-x + 4 = 0
4 = x
