Answer:
Step-by-step explanation:
The question is 10b/(2b + 8)
The reciprocal will not make a minus sign. B and C are both wrong. Powers can create a minus sign but not this kind of question
Two terms creating a binomial must stay together. In this case (2b + 8) must be entirely in the top or bottom of the fraction. That makes D wrong.
Answer: A is the correct reciprocal.
