That one is for Windows users. 
I see a 1366 x 768 laptop there. I use KDE, much less dumbed down than the regular Ubuntu. Is that the gnome desktop now or is it still Unity?
Either way if alt-left-click click and drag will not move a window up and off the display, then use the gnome version which is 'Win key`-left-click and drag.

For resizing, if the corner / edge handles are not easy to use, try a right click in the window title bar which gives a resize option. https://i.imgur.com/WzHdmTS.jpg
If a gnome desktop you might need to turn edge snapping off. Try in a terminal (one at a time)
Now this one is demonstrated in Windows but is equally applicable to linux
