8 0

Answer:

A

Step-by-step explanation:

Starting with the original equation:

\sqrt{1-3x} =x+3

Squaring both sides to remove the root, and expanding the right side:

1-3x=(x+3)(x+3)

Multiplying the right side:

1-3x=x^{2} +6x+9

Combine like terms:

x^{2} +9x+8

Factor:

(x+8)(x+1)

If x+8=0, then x= -8

If x+1=0, then x=-1
