Answer

Option D is correct.

x = 6

Explanation

9 : x = x : 4

To solve this, we know that ratios can be written in fraction form

(9/x) = (x/4)

[tex]\begin{gathered} \frac{9}{x}=\frac{x}{4} \\ \text{Cross multiply} \\ x^2=9\times4 \\ x^2=36 \end{gathered}[/tex]

Take the square root of both sides

√(x²) = √(36)

x = 6

Hope this Helps!!!
