Simplify -|-5 + 2|.
A)-7
B)-3
C)3
D)7
To simplify the expression -|-5 + 2|, we need to follow the order of operations, which states that we should calculate the absolute value first, and then the negative sign.
The absolute value of a number is the distance of that number from zero on the number line. So, |-5 + 2| means we need to find the absolute value of -3.
The absolute value of -3 is always positive, so it is equal to 3.
Therefore, the simplified expression is -3.
So, the correct option is B) -3.
