6
Step-by-step explanation:
When you multiply the square root of something with itself, your answer will be the number inside the radical sign.
This means that we should get 3*2=6.
Answer:
Rate of change of the area of the square is 42 units at t = 2.
Step-by-step explanation:
We note that the area of the square is given by:
but we aim to find
. But we can use the chain rule to pull out that dA/dt. Doing so gives us:

Now,
(by the power rule and 
But since we have "x" and not "t", we want to find what x is when t = 2. Substituting t = 2 gives us x(2) = 3(2) + 1 = 7.
So, finally, we see that:
