Answer:
12^2 + 4x
Step-by-step explanation:
We need to solve the area of these two rectangles separately.
Equation: 4x(3x+1) --> 12x + 4
Area: 12x^2 + 4x
Hope this helps.
Answer:
A. $18
B. $200
C. 
Step-by-step explanation:
Function:

<u>Parts A and B:</u>
The price that generates the maximum profit is ate vertex of parabola. Find the coordinates of the vertex:

The price that generates the maximum profit is $18
The maximum profit is $200
<u>Part C:</u>
The company breaks even when the profit is positive. From the graph of the function you can see that the graph of the function is over p-axis for all
, so the positive profit is for 
In p=16 and p=20, the profit is 0 and when p<16 and p>20, there will be a loss.
