7 different ways is the answer
Answer:
342 units squared
Step-by-step explanation:
since this is a rectangular prism, all we have to do is multiply the values by one of the other values once and multiply that by 2
I suppose you mean

Differentiate one term at a time.
Rewrite the first term as

Then the product rule says

Then with the power and chain rules,

Simplify this a bit by factoring out
:

For the second term, recall that

Then by the chain rule,

So we have

and we can simplify this by factoring out
to end up with

The range is the high and low points.
So (5, 2]
