Given:
To find:
The missing value.
Solution:
Let x be the missing value.
We have,
Subtract from both sides.
Multiplying both sides by 5, we get
So, the missing value is 3.
Therefore, the correct option is C.

Answer:
The base is decreasing at 2 cm/min.
Step-by-step explanation:
The area (A) of a triangle is given by:
(1)
Where:
b: is the base
h: is the altitude = 10 cm
If we take the derivative of equation (1) as a function of time we have:
We can find the base by solving equation (1) for b:
Now, having that dh/dt = 1 cm/min, dA/dt = 2 cm²/min we can find db/dt:
Therefore, the base is decreasing at 2 cm/min.
I hope it helps you!
