Can I use my backcountry touring poles for resort skiing too?

Yes, touring poles work fine for resort skiing—just set them to your preferred downhill length and ski normally. They may feel slightly heavier and less stiff than dedicated fixed-length alpine poles, but the difference is minimal for most recreational skiing. The powder baskets will be slightly more cumbersome on groomed runs but not problematic. Many skiers use one pair of adjustable touring poles for everything, which is practical and economical. However, if you race or ski very aggressively at the resort, you may prefer the stiffer, lighter feel of dedicated fixed-length poles for resort days.
