One correct answer:
D
Because all of the sides are even, and it has no 90 degree angles.
The geometric mean is defined as the nth root of the product of n numbers
1. 4 and 9
Geometric mean = 
2. 5 and 8
Geometric mean = 
3. 8 and 32
Geometric mean = 
4. 64 and 36
Geometric mean =

Answer:
B
Step-by-step explanation:
V=1/3Bh
v=1/3s^2 (1/2s)
v=1/6s^2
The first one is a proportional relationship.
Answer:
Step-by-step explanation:
If the coordinates are (0, a) and (b, 0), we just use the distance formula to find the distance in terms of a and b:
and
which simplifies to

and that's it!
