Answer:

Step-by-step explanation:
can be solved by just multiplying the numerators together and the denominators together
2 * 3 = 6 and 5 * 4 = 20 so the answer would be 
This simplifies to 
True.
The square root of 12: √12 = 3.464101......
This continues indefinitely and can not be represented as a ratio of two integers.
So it is not rational, that is irrational.
Answer
17 m^3
Explanation
Volume of a given prism = bh
Where b = base area and h = height of prism
Base area = 1 • 2/2 (b • h /2)
= 1
Height = 17
17 • 1 = 17 m^3
Assuming the possible digits are from 0-9, there are 10*9*8 possibilities which come out to 720
