Answer:

B. -0.9, 8.9

Step-by-step explanation:

The value(s) of the variable can be found by undoing the operations done to it.

Undo the square by taking the square root:

x -4 = ±√24 = ±2√6

Undo the subtraction by adding 4:

x = 4 ±2√6 ≈ {-0.8990, 8.8990} . . . keep enough digits to round correctly

The approximate solutions are ...

-0.9, 8.9
