Answer:

B. 4

Step-by-step explanation:

We have the equation x^2 = 16 and we want to solve for x.

Square root both sides:

\sqrt{x^2} =\sqrt{16}

x = +/- 4

A rational expression is considered undefined when the denominator is equal to 0 (in other words, we get something like k/0, which is undefined). Here, the because 3x^2-48=0 when x = 4, then the answer is B.

Hope this helps!

Answer:

Step-by-step explanation:

3x² - 48 = 0

3x² = 48

x² = 16

x = +/ 4

From the given choices, it's x = 4
