Answer:
4
Step-by-step explanation:
We need to isolate x. We first need to get "rid" of the radical. Since the square root is found by finding a factor that multiplies itself to equal that number we would find the square.
sqrt x + 2 ^2 = 5^2
x + 2 = 25
Now we subtract 2 from each side.
x = 23

Step-by-step explanation: The correct way to calculate what percentage more attended the play is to first subtract the expected number from the actual number. 15 - 10 = 5 more attended than was expected. Next, you need to divide the 5 additional people by the 10 that were originally expected. 5 divided by 10 = 50%
