Answer: C
Explanation:
Im going to put this answer in simple terms because I don't want to confuse you too much with a big explanation on a question that doesn't need one.
Anyway, the answer to the equation is C, stating that |A| > 0. If you were wondering, the two lines on either side of the a are absolute value bars. To put it in simple terms, when you put a negative number in between absolute bars, the number because positive. However, when you put a positive number in between, the number stays the same. SO...
The value of A on the number is 4. SO...
Substitute: |-4| > 0
Solve: 4 > 0
Because it is true that 4 is greater that 0, the answer is C.
Hope this helps!
