Can you help me on these kinematic physics problems?

25=5+10a=>a=2
I’m not sure if you can solve that…you’re given an object starts at rest and travels for 10 seconds, and you have to find the distance it travels without velocity or acceleration?
120=20t+5t^2, solve the quadratic
-v0=v0+2t=>t=-v0=>t/s=-vo/2
vf=v0, x=v0t, vf^2=v0^2
