hi please tell me the answer. for this question and give me study notes concepts for math. Thank you

I don't know if this will help you now, but I still suggest to practice on foundations until it is very strong and try out a variety of different questions. Check your work after you are done, make sure there are no mistakes and do each question again if there is time in the examination. If there are challenging questions, try to use the information in the question to at least form one of two equations.
