Answer:
8, 4, and 2 can not be the lengths of the sides of a triangle.
Step-by-step explanation:
If a and b are the two side's length of a triangle then the length of the third line (c) will be governed by the relation
(a+ b) > c > (a - b)
Now, the two sides length of a triangle are given by 8 and 4 then the length of the third side (x) will be given by
(8 + 4) > x > (8 - 4)
⇒ 12 > x > 4 ........... (1)
But here the third side length is 2 which does not satisfy the above condition (1).
Hence, a triangle can not have side lengths 8, 4, and 2. (Answer)
Imagine there are 8 spots on the shelf. Replace the volumes one by one.
The first volume to be replaced could go in any one of the eight spots.
The second volume to be replaced could then go in any one of the seven remaining spots.
The third volume to be replaced could then go in any one of the six remaining spots.
etc
So the total number of ways the eight volumes could be replaced
= 8!
= 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 40,320
