It all depends on the math question but usually you solve for x, then check it. Plug x back in and see if it works. But it all depends on the math problem
Answer:
$204
Step-by-step explanation:
The question is at what price x will the company maximize revenue.
The revenue function is:

The price for which the derivate of the revenue function is zero is the price the maximizes revenue:

The company will maximize its revenue when the price is $204.
All the numbers are multiplied by 2 or doubled.
So the missing number after 2 is 4.
After 16 is 32.
We have that
x²<span> + 7x + c
</span><span>Group
terms that contain the same variable
</span>(x² + 7x )+ c
<span>Complete
the square. Remember to balance the equation
</span>(x² + 7x+3.5² )+ c-3.5²
Rewrite as perfect squares
(x+3.5)²+ c-3.5²
so
c-3.5² must be zero
c-3.5²=0------- c=3.5²------> c=12.25
the answer isthe value of c must be 12.25
=(5x+4)°
=(2x-2)°
=(4x-6)°
we know that,
=
+
According to the question,
so,
=(4x-6)°=(4×12-6)°=(48-6)°=42°
