## Intermediate Algebra (12th Edition)

(a) We know that two negatives cancel, so: $-(-4)=4$ This corresponds to choice A. (b) We know that an absolute value makes numbers positive, so: $|-4|=4$ This corresponds to choice A. (c) Based on the previous result, we have: $-|-4|=-(4)=-4$ This corresponds to choice B. (d) Combining previous results, we get: $-|-(-4)|=-|4|=-4$ This corresponds to choice B.
