Answer:
For #9, the part of the expression that represents the quotient is the division problem in parenthesis. Specifically, "(45 ÷ 9)". I believe you only need the division symbol for this, though. Correct me if I'm wrong.
As for #10, the part of the expression representing the product of two factors is 5.2 being multiplied by the variable [tex]u[/tex]. This results in the the term [tex]5.2u[/tex], with the coefficient being 5.2 and the variable being [tex]u[/tex].
