The other two volumes correspond between 1in and 35 in.
The given expression is:
4 - 8 (3/4) + 1/4
To start, we will convert all the numbers to be having a denominator of 4 as follows:
4 is equivalent to 16/4
-8 (3/4) is equivalent to -24/4
1/4 already has 4 as a denominator
Now, the new expression became:
16/4 - 24/4 + 1/4
Since they all have a common denominator, the result can be computed by adding numerators as follows:
16/4 - 24/4 + 1/4
= (16-24+1) / 4
= -7/4
The correct choice is:
A. -7/4
There are a couple of ways you can solve this. You can write it out like
(K-3)(K-3)(K-3)(K-3)(K-3)(K-3)(K-3)
And pretty much use the foil method
Or you can use the binomial theorem (google it if you dont know)
The solution should be:
(K^7) - 21(k^6) + 189(k^5) - 945(k^4) + 2835(k^3) - 5103(k^2) + 5103k - 2187
