We have been given an equation
x+4=x^2. We are also told that x is greater than 0. We are asked to choose the equation that can be written as our given equation.

Since x is greater than, so we will take positive root on both sides of our given equation as:


√(x+4)=√(x^2)


√(x+4)=x

Upon looking at our given choices, we can see that option C is same as our answer.

Therefore, option C is the correct choice.
