Step-by-step explanation:
From your problem statement, I believe the equation will look like this:

The slash means "divided by" -- you should use division to solve this equation.
For division involving exponents with the same base, you can use the following rule:

Subtituting
for
,
for
and
for
, we get the following:

If you want to multiply (2*x + 5) and (2*x - 5), you can do this using the following steps:
(2*x + 5) * (2*x - 5) = 4*x^2 - 10*x + 10*x - 25 = 4*x^2 - 25
The correct result is 4*x^2 - 25.
None of those describe this function.
It's not a constant function, because it is not equal to a constant (something that isn't a variable)
It doesn't show direct variation, because it can't be represented in the form
y = kx.
It isn't an absolute value function because the absolute value isn't taken anywhere.
If it was an absolute value function it would look something like this:

It isn't a greatest integer function, because the greatest integer isn't taken anywhere.
If it was a greatest integer function it would look something like this:

Are you sure you typed that question right?
Answer:
n=11
Step-by-step explanation:
Solve for n by simplifying both sides of the equation, then isolating the variable.
