Answer:
Step-by-step explanation:
First off, let's change everything to a common denominator. This will allow us to add the fractions!
To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.
Let's change the first fraction into a number with a denominator of 28!
= 1. Multiplying a number by one doesn't change its value.
The second fraction, 
, already has a denominator of 28, so we don't have to do anything with it.
Now to the third number, -1:
Now, let's add them all up!
One last step, to simplify:

Okay and... what are you confused about
Answer:
The formula to find the voltage is:
And the voltage is 4 volts
Step-by-step explanation:
To get the equation of voltage you need to isolate v in one side of the equation. In order to do that, you need to remove the divisor/denominator and its square. How will you do that?
First, multiply both sides with R:
That would result into removing the divisor R from the right side of the equation:
Next, square-root both sides:
That would result in removing the square of v from the right side of the equation:
Thus we get the equation, .
To find out the voltage, simply replace R with 32 and P with 0.5
Thus, the voltage is 4 volts.
