The area of the square increasing at 30 
The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another
Let the side of a square be x.
So,
Area of square = 
A =
Differentiating with respect to time we get,
dA/dt = 2x dx/dt
When area = 9 
the side becomes 3 cm
At x = 3cm and dx/dt = 5 cm/s (Given)
dA/dt = 2.3.5 = 30
Thus the area of the square increasing at 30

Step-by-step explanation:
<u>Step 1: Define</u>
2x < -10
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 2 on both sides: x < -5
Here we see that any value <em>x</em> smaller than -5 would work as a solution.
<u>Step 3: Identify</u>
<em>Answer choices.</em>
I. -2
II. 2
III. 10
We see that none of these numbers are less than -5. Therefore, non of the answer choices are correct.
