Answer:
x=-1
Step-by-step explanation:
The lines stand for absolute value ( how far a number is from 0), so each number should be a positive, then you just solve for x. Isolate x, then divide on both sides, and you should get -x=1, which is equal to x=-1.
Hence the correct answer is C) -23
Further explanation:
We have to put the values of m and n into both expression first separately and then multiply the answers.
Given expressions are:

The values are:

Putting the values in expression 1:

Putting the values of m and n in second expression

Multiplying both expressions:

Hence the correct answer is C) -23
