I need help ASAP and for the work to be shown

Answer 1

Answer:

x=142

Step-by-step explanation:

The given equation is:

`\frac{\sqrt[]{x+2}}{3}=4`

Cross multiply

`\begin{gathered} \sqrt[]{x+2}=3(4) \\ \sqrt[]{x+2}=12 \end{gathered}`

Square both sides

`\begin{gathered} \sqrt[]{x+2}^2=12^2 \\ \end{gathered}`

Note that the root cancels the square root

`x+2=144`

Collect like terms

`\begin{gathered} x=144-2 \\ x=142 \end{gathered}`
