Answer, if you do i need an a good one on how to asnwer question like these

Her first mistake was in step 2.

When taking an absolute value of some number let’s say x, equals to the distance it is from 0
So |x| = x as well as |-x|=x because they have the same distance from 0. 2 and -2 are both 2 unit from 0.

So in the problem, her second step was to add |-2| and |6| to get her first distance. She was supposed to remove the | | by taking the absolute value of |-2|, which is makes the equation 6+2 because |-2|=2. She just removed the signs without applying the function. Her answer should’ve been 8 for that distance not 4. Therefore her area should have been 32, not 16.
