Please help me in this homework:

With reference to Berk, J. and DeMarzo, P., (2014), Corporate Finance, how do investment, financing and dividend decisions relate to the company's goal of maximizing value? (This is not contained in one chapter, but rather is a conclusion to all articles) The answer should not exceed half a page.

In addition, What are the payout policies adopted by firms? (This can be answered by reading chapter 17 ) the answer should not exceed 1 page.
