it's either a or b, not sure but I think it's b
The exact value of the expression is 163.98 :)
The expression which is not equivalent to (8 + (n - 4)) is (12+n) and this can be determined by using the arithmetic operations.
Given :
Expression - 8 + (n - 4)
To simplify the given expression following steps can be used:
Step 1 - Rewrite the given expression.
= (n - 4) + 8
Step 2 - Now, remove the parenthesis in the given expression.
= n - 4 + 8
Step 3 - Now, write 8 as the addition of 4 and 4.
= n - 4 + 4 + 4
Step 4 - Subtract 4 by 4.
= n + 4
Therefore, the correct answer is (12+n).

This is a Logic Problem. So we need to use operators to solve this problem. There are several operators in logic. Operators can be <em>monadic</em> or <em>dyadic</em>. A monadic operator operates on a single simple statement. Other operators will all be dyadic operators <span>because they operate on two simple statements. So in this problem we have the following operators:
</span>
1. The negation operator:
<u>Symbol:</u> ~
<u>Symbol name:</u> Tilde
<u>Parts of negation</u><span><u>:</u> A simple statement with a tilde preceding it</span>
2. Conjunction:
<u>Symbol:</u> &
<u>Symbol name:</u> Ampersand
<u>Parts of conjunction:</u> <span>Two simple statements joined by the conjunction symbol.
</span>
So we can name the statements as follows:
A: I am at home
B: I am playing video games
So the translations is as follows:
~(A&B) = It is not the case that I am at home and am playing video games
