Answer:
1. The determinant is 8.
2. The determinant does not depend on the variables in the matrix.
3. When there are zeroes below the main diagonal, the determinant is the product of the diagonal.

(If this is what i think it is)
First, put them directly above each other.
5a+2s=48
3a+2s=32
You need to combine these, but in order to do so, we want to get rid of one of the letters. The S's line up very well, and all we need to do is multiply the bottom equation by a negative 1. This will look like this,
-3a-2s=-32 (and add it to the other equation)
5a+2s=48
This gives you
2a=16
Divide both sides by 2 to get a by itself.
a=8, is your answer!
If it asked for s, you would put 8 into whichever equation seems easier for you, and then its just simple crunching it out.
Hope this helped!
Right away, you can tell that the number is greater that one if the exponent is positive. For example, 1.23 x 10 to the power of 2 would be 123, which is greater than 1. If the exponent is negative, the answer will most likely be less than 1. For example, 1.23 to the power or -2 would be .0123.
