Answer:
x=8
Step-by-step explanation:
The ratio of the sides is 7:14=1:2. So, the ratio of DF:XZ is 1:2. DF=2x-5, and XZ=22. This makes the ratio. 2x-5:22=1:2. That means 2x-5 is half of 22, which is 11. We can solve from there.
- 2x-5=11
- Add 5, 2x=16
- Divide by 2, x=8

This is one time when I'm going to ignore my own #1 Cardinal Rule for answering questions on this site. Normally I'm totally against simply dumping an answer without explaining how I got it. In this case, however, I never found the short, easy, clever way to answer this one. I just slogged through all of the 473 multiples of 19 that have 4 digits, and weeded out the ones that don't fit your specifications. I used a popular office software program to grease the process, but even so, there absolutely must be a better way to do it, and I would not wish this one on you, so I'm not going to describe it.
I'm grateful for your 5 points. The crust and warm cloudy water are delicious.
