Questions have a 4-day open period. If your question doesn’t receive any answers within this time frame, it will expire and be deleted. However, before the question expires, you have the option to extend the time period a question is open. You can extend it one time by 4 more days to a total of 8 days.

To extend the open period for your question:

1. Go to the question, click Edit (pencil icon) in the action bar below the question, and select Extend Expiration from the option menu.

If nobody answers your question after 8 days and your question expires, you can try rewording your question and asking it again or search Yahoo!7 Answers to see if anyone else has received an answer to a similar question.
