Infinitely many.
Choose any number X such that 0 < X < sqrt(20) and let Y = 20/X.
Then X*Y = X*20/X = 20 and since X was selected arbitrarily, there are infinitely many possible answers to the question.

What two whole numbers make -20?
There are infinitely many answers. Let A be any whole number and let B = -A -20 Then by the closure of integers, B must be a whole number. And A + B = A + (-A - 20) = -20 Since A is arbitrary, there are infinitely many ways of choosing A and so there are infinitely many ways in which two whole numbers will make -20.
