srry theres no pic :(
this is one of the accuplacer questions

anonymous · Answer

Accuplacer - that is a placement test, isn't it? If so, you may not want to be getting help on those questions because that will cause you to be placed in a math class that you are not ready for. 
And sorry, I don't understand the question. Perhaps you can provide a screenshot, if you still need help with this question.
