Question

3x squared =118. Solve the equation. Round to the nearest hundredth if necessary.

Answer 1

Answer:

3.62

Step-by-step explanation:

118 square rooted is 10.86

10.86/3 = 3.62

Answer 2

Answer:

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

Step-by-step explanation:

Given equation:

$3x^2=118$

Divide both sides by 3:

$\implies \dfrac{3x^2}{3}=\dfrac{118}{3}$

$\implies x^2=\dfrac{118}{3}$

Square root both sides:

$\implies \sqrt{x^2}=\sqrt{\dfrac{118}{3}}$

$\implies x=\pm\sqrt{\dfrac{118}{3}}$

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