Answer:
D. -N
Step-by-step explanation:
Our four given expressions are:
A. |-N|
B. -(-N)
C. |N|
D. -N
The | | symbols represent absolute value, which is the distance from the value within the two lines and 0; essentially since it measures distance, absolute value always outputs a positive value.
In choice A, we have |-N|, which means the distance between -N and 0. Well, the distance will simply be N, which is equal to N. Eliminate A.
In choice B, we have -(-N). Double negatives signal that they will cancel out to become positive, so -(-N) = N. Eliminate B.
In choice C, we have |N|, which means the distance between N and 0. This is clearly just N, so eliminate C.
In choice D, we have -N, which denotes "negative N". Clearly, "negative N" (-N) is not the same as "positive N" (N), so D is the answer.
