How do you calculate a net worth statement?
marissa [1.9K]

Answer:

a. Assets - Liabilities

Step-by-step explanation:

Assets/Liabilities is a management method to minimize risk. So, it cannot be the answer.

There is no formula like "Assets + Liabilities" and "Assets x Liabilities" in accounting to calculate the net worth. Therefore, those can be eliminated.

We know that net worth is calculated by deducting all liabilities (long-term and short-term) from net assets. Therefore, option (a) is the correct answer.

Can somebody help me with this ?? :)
Alex777 [14]

Answer:

Your answer would be D, the equation is a function because it is a polynomial and all polynomials are functions.

Step-by-step explanation:

I like to remember that polynomials have no negative , fraction exponents and no division. In this case everything is positive so I knew it was a polynomial , and like the answer says all polynomials are functions !

Hope this helped
