Answer:

B

Step-by-step explanation:

Given

[tex]\sqrt{x-6}[/tex] + 5 = 12 ( subtract 5 from both sides )

[tex]\sqrt{x-6}[/tex] = 7 ( square both sides )

x - 6 = 49 ( add 6 to both sides )

x = 55

Answer:

B. Subtract 5 from both sides and then square both sides.

Step-by-step explanation:

First, subtract 5 from both sides in order to get [tex]\sqrt{x-6}=7^{2}[/tex]

Second, square both sides in order to get [tex]x-6=49[/tex] (p.s. squaring both sides gets rid of the square root)

Third, add 6 to both sides in order to get x=55

Last, see that the answer is B, as you had to subtract 5 from both sides and then square both sides to get your answer

There you go, and good luck on the other questions!
