That's about as much as you can simplify this problem.
I hope this helps! :)
Answer:

Step-by-step explanation:
<u>Functions</u>
In a function, an independent variable, let's call it x is related to a dependent variable y and it can be expressed as:
y = f(x)
Let's consider the functions given in the question, where the equation that represents a company's yearly sales is:

And the equation that represents the same company's yearly expenses is:

The company's profit function P(x) can be found as the difference between S(x) and E(x), thus:

Operating:

Simplifying, the profit function for this company is:

When two straight lines cut each other vertical angles are formed. There are two pair of vertical angles .Vertical opposite angles are always equal .
In the figure Substituting the values of the angles given.
x+40=3x.
Subtracting x both sides.
40=3x-x
40=2x. Dividing both sides by 2.
X=20.
Try 2 because it’s surface area
hope that helps xo
