Answer

-4

Work Step by Step

We first consider what is within the absolute value bars. 30-28 equals 2. However, because the straight lines that enclose the expression 30-28, we know that we are supposed to find the absolute value, meaning that we take whatever number we get and make it positive. However, 30-28 is 2, which is already positive, so we do not have to worry about the absolute value bars. Then, we subtract 6 to obtain the answer: -4.
