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:
I hope it helped u.
Step-by-step explanation:
B.) because according to the identity property of addition, any number added to zero will remain the same.
HOY = Horizontal line, m=0, y is the only variable in the equation
VUX = Vertical line, m= undefined, x is the only variable in the equation
