Answer:
250
Step-by-step explanation:
First, we need to find h°g, which is the same thing as 
This means that we will take the function
and will replace each instance of x with
as that is the value of 

Now that we have our composed function, we can find the y-value when 

<span>Setting expressions equal to one another gives us an equation.
In an equation, our goal is to isolate the variable; we must "undo" everything that has been done to the variable. We work backward; the last thing done to the variable will be the first thing we undo.
We "undo" things by performing the opposite operation; for instance, if the last thing done to our variable was that 3 was subtracted from it, we would undo that first by adding 3 to both sides.
What we do to one side we must do to the other in order to preserve equality.
We would continue this process of working backward until the variable was isolated; this would give us our solution.</span>
