To find \( x \) using the geometric mean, we typically use the formula for the geometric mean of two numbers \( a \) and \( b \), which is given by:
\[ x = \sqrt{a \times b} \]
However, you haven’t provided the values of \( a \) and \( b \). Please provide those numbers, and I will calculate \( x \) for you, rounding the answer to the nearest tenth.
