A:Answer Yes and No. The eero cannot wirelessly extend a non-eero wifi network. So, if you hardwire this eero to your Airport Extreme, setup the eero and put the eero into bridge mode, the eero will create a wifi network for your device to connect to. Since the eero is bridged it have the Airport Extreme handle all the networking tasks, the eero will just do wifi. Devices on the eero wifi will be able to talk to stuff connected directly to the Airport Extreme. If you are wanting more range you can then use additional eero (they will connect to the head/gateway eero wirelessly or wired) and those eero will broadcast the same wifi.
