Are you asking about the apps that came pre-installed with the tablet?
If so, you will have to root your tablet to uninstall them permanently. Unfortunately I cannot find any information online on how to root your particular tablet.
This link may be of some interest to you, if the tablet's OS is Android KitKat. If it is Lollipop, Jellybean or below you need to root your tablet as this doesn't work for those OSs. It details how to block bloatware on Android devices by using a debloater tool developed by XDA Developers.
Hopefully this is of some help.
