You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.
Negative exponents work the same as positive ones, except you have to consider the inverse of the base.
So, if for example 
, in the same fashion you have
So, negative exponents lead to a fraction with numerator 1 and denominator the same expression, but with positive exponent.
So, in your case, let's work with the inner parenthesis first:
Now, if we want to raise this to the negative two, we have
Answer:
0
Step-by-step explanation:
The value of x would be 15 degrees.
This is a right angle and right angles are 90 degrees in total.
90-30= 60
We know that the missing part of the angle equals 60 degrees so we divide 60 by 4x.
60/4x=15.
I hope that was clear enough, sorry if it’s not. Have a great day and good luck!
