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:

Answer:
D: humor.
Step-by-step explanation:
it's just common sense. I am not a gen z so I should know.
252 dollars. (First you find how much is being added each week, it’s 24 dollars, then you multiply it by 18, and get 252.)
That would be 74 because when you divide 148/2=74
