Then? I think there's more to the question
I think the current age of the child is 16 and the father is 40. That would mean 4 years ago the father was 36 and the child was 12. This makes the father 3 times as old as his son four years ago.
You can identify an expression by the number of the terms in the expression.
monomial = one term
binomial = two terms
and so on.
y contains only one term, so it is a monomial.
9q +
-
contains three terms, so it is a trinomial.
