Solve. \( \sqrt{7 x}=14 \) Select the correct choice below and, if necessary, fill in the ans

To solve the equation \( \sqrt{7x} = 14 \), first square both sides to eliminate the square root. This gives us: \( 7x = 196 \) Next, divide both sides by 7: \( x = \frac{196}{7} = 28 \) So, the solution is \( x = 28 \). For further verification, let's plug the value back into the original equation: \( \sqrt{7 \cdot 28} = \sqrt{196} = 14 \), which holds true. Thus, \( x = 28 \) is the correct answer!
