Answer 1

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

Explanation:

First, subtract 5 from both sides in order to get
`√(x-6)=7^(2)`

Second, square both sides in order to get
`x-6=49` (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!

Answer 2

B

Explanation:

Given

`√(x-6)` + 5 = 12 ( subtract 5 from both sides )

`√(x-6)` = 7 ( square both sides )

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

x = 55
