The equation which is equivalent to √x + 11 = 15 is: C. √x = 15 - 11.
Given the following equation:
To evaluate the given mathematical equation:
In this exercise, you're required to evaluate the given mathematical equation. Thus, we would make x the subject of formula in the equation and then simplify as follows:
√x = 15 - 11 (equivalent)
√x = 4
Taking the square of both sides, we have:
x = 4²
x = 16.
