I'm assuming all of (x^2+9) is in the denominator. If that assumption is correct, then,
One possible answer is 
Another possible answer is 
There are many ways to do this. The idea is that when we have f( g(x) ), we basically replace every x in f(x) with g(x)
So in the first example above, we would have

In that third step, g(x) was replaced with x^2+9 since g(x) = x^2+9.
Similar steps will happen with the second example as well (when g(x) = x^2)

Here we have to convert 423 yards into feet.
first let us find the basic relation between yard and feet
1 yard =3 foot
so applying this to our question we get,
423 yard =423*3 foot = 1269 feet
Answer 423 yards =1269 feet
The answer is 5 feet I think
