Since both rectangles are similar, the following ratio must be fulfilled:
![\frac{x+9}{14}=\frac{9}{6}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B9%7D%7B14%7D%3D%5Cfrac%7B9%7D%7B6%7D)
By multiplying both sides by 14, we get
![\begin{gathered} x+9=\frac{9\times14}{6} \\ x+9=21 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%2B9%3D%5Cfrac%7B9%5Ctimes14%7D%7B6%7D%20%5C%5C%20x%2B9%3D21%20%5Cend%7Bgathered%7D)
and by subtracting 9 to both sides, we have
![x=12](https://tex.z-dn.net/?f=x%3D12)
Therefore, the answer is 12.

Answer:
D. The axis of symmetry is the y-axis.
Step-by-step explanation:
The vertex is at coordinates (0, 3). Since this parabola opens vertically, its axis of symmetry is the x=coordinate of the vertex: x = 0. That is the equation of the y-axis.
The axis of symmetry is the y-axis.
