B. x=13
C. x=43
D. x=55

Answer 1

its x=55

i just took the quiz

Answer 2

D. x=55

Step-by-step explanation

The given radical equation is

`√(x - 6) + 3 = 10`

Add -3 to both sides

`√(x - 6) = 10 - 3`

`√(x - 6) =7`

Square both sides.

`{ (√(x - 6))}^(2) = {7}^(2)`

`x - 6 = 49`

Solve for x to get:

`x = 49 + 6 = 55`
