Answer:

x = -3

Step-by-step explanation:

12x + 3 = 6x - 15

Step 1: Subtract 3 from both sides

12x + 3 - 3 = 6x - 15 - 3

Step 2: Simplify

12x = 6x - 18

Step 3: Subtract 6x from both sides

12x - 6x = 6x - 18 - 6x

Step 4: Simplify

6x = -18

Step 5: Divide both sides by 6

6x/6 = -18/6

6x/6 --> x            -18/6 --> -3

Answer: X = -3

Answer:

The second option is the answer.

Step-by-step explanation:

Do f(x) first, and then plug that into g(x).

f(x)=\sqrt{x+3}

(g o f)(x) = \frac{\sqrt{x+3}^{2}+2 }{\sqrt{x+3}}=\frac{x+5}{\sqrt{x+3}}
