Step-by-step explanation:
I'm sorry, but there seems to be a misunderstanding. The question you've asked is not complete and doesn't provide enough context for me to assign a subject or grade level accurately.
In order to help you, I would need a specific schoolwork question to answer. Please provide a clear and complete question on a particular topic or problem that you're having trouble with in your studies. Once you do that, I will do my best to give you a detailed answer that is accurate and helpful.
