Explanation for Question 5 From the Math (No Calc) Section on the 2019 April Sat
For number five, we were given the square root of X plus four equals 2 12, and we were looking for the solution to the equation. 3 So we're basically solving for X here to solve for X. 4 We need to get it alone on one side. 5 And the first step would be to subtract four from both sides. 6 So that would leave us with squared of X equals eight, 7 and then to finish getting X alone, 8 we can just square both sides. 9 So that leaves us with X equals 64, 10 which is C.
