Final answer:
PNG, GIF, and TIFF are image file formats that support transparent backgrounds.
Step-by-step explanation:
The image file formats that support transparent backgrounds are PNG (Portable Network Graphics), GIF (Graphics Interchange Format), and TIFF (Tagged Image File Format).
These formats allow you to have parts of the image be transparent, which means you can see the background behind them. For example, if you have a logo with transparent background, you can overlay it on another image or document without the background obscuring the underlying content.
PNG, GIF, and TIFF are image file formats that support transparent backgrounds.
Now, since we don't have the specific value for x, we need more information to solve for the individual ages. If you have additional information about the relationship between Nepo's age and his father's age (e.g., the difference in their ages), we can use that information to solve for the values of N, S, and F.
