Answer:4x
Step-by-step explanation:
Answer:
See detail below.
Step-by-step explanation:
A word of caution before getting to the actual problem: I believe there is an important set of brackets missing in the original post. The expression on the left hand side should be:
(cosxtanx-tanx+2cosx-2)/(tanx+2)
Without the brackets, it is left unclear whether the denominator is just tanx or tanx+2. I recommend to use brackets wherever any doubt could arise.
Now to the actual problem: \we can make the following transformations on the left hand side:

which is shown to be the same as the right hand side, which was to be shown.
Answer:

The solution for
is all real numbers less that or equal to 36.
Step-by-step explanation:
Given expression:

To find the solution for 
Solution:
In order to solve for
, we will make sure to isolate the unknown variable
on left side alone by doing math operations on both sides of the inequality.
We have:

Multiplying both sides by 2.

The 2 on left side will cancel each other leaving
alone.
Thus, we have:

Thus, solution for
is all real numbers less that or equal to 36.
