Answer:


x=\pm6.27\: \textsf{(nearest hundredth)}

Explanation:

Given equation:


3x^2=118

Divide both sides by 3:


\implies (3x^2)/(3)=(118)/(3)


\implies x^2=(118)/(3)

Square root both sides:


\implies √(x^2)=\sqrt{(118)/(3)}


\implies x=\pm\sqrt{(118)/(3)}


\implies x=\pm6.27\: \textsf{(nearest hundredth)}
