First find the side lengths of the box by factoring each area:
12: 1, 2, 3, 4, 6, 12
15: 1, 3, 5, 15
20: 1, 2, 4, 5, 10, 20
Find 3 numbers that both have 2 sides have in common and can multiply to make the areas of the faces:
12: 3 * 4
15: 3 * 5
20: 4 * 5
Sides: 3, 4, and 5
Then multiply to get the volume:
3 * 4 * 5 = 60 units^2
Answer:

Step-by-step explanation:
The first step is to find the slant height of the cone. Using the pythagorean theorem, you can find that
cm. Plugging this into the equation, you get
. Hope this helps!
Answer:
I would say that they are different because if x - a has a value to the equation then that means a - x will not have the same value because it may be rearranged to a different equation but that doesn't mean that they will have the same value. that explain why x - a and a - x are not the same
The square root of 7 is an irrational number.
Answer:
Eliminating the parameter, the equation is 
Step-by-step explanation:
We are given the following parametric equations:


We want to eliminate the parameter t. From the first equation:


Replacing in the second equation:


Eliminating the parameter, the equation is
