\( v= \) uwt \( u=\square \frac{\square}{\square} \)

It looks like you're working with some equations involving variables \( v \) and \( u \). However, the equation for \( u \) is incomplete, as it contains placeholders (squares) that need to be filled in. To help you better, could you please provide more context or clarify what you would like to achieve with these equations? For example, are you looking to solve for one of the variables, or are you trying to express one variable in terms of the others?
