EXPLANATION
The revenue function is

The cost function is,
C=600-50t
In order to break even, revenue must be equal to cost.

Group every term on the LHS.


Divide through by 50.

Factor to obtain,


The answer is A = 2x² + 6x - 20
The area of the rectangle is:
A = l * w
l = x + 5
w = 2x - 4
A = (x + 5)(2x - 4)
Use the distributive property to calculate this:
A = (x + 5)(2x - 4)
A = x * 2x + x * (-4) + 5 * 2x + 5 * (-4)
A = 2x² - 4x + 10x - 20
A = 2x² + 6x - 20
