Laplace tranform and inverse of Laplace transform

Hello. I just want to check if my exercise are right:

L(x+e^{-x})=1/s^2+1/(s+1)

Inverse of these Laplace transform

F-1(1/(p-2))= e^(2s)

F-1((e^(-2p))/(p^2))=2/(s^3)*(s+2)

F-1(p^2+4p+5)= e^(-2s)*cos(s)

F-1(p/(p+1)^2)=e^(-s)/s^4

F-1(e^(-p))=1/(s+1)


Can you just confirm that this results are right and if not please tell me the right solution and how to get there??
Thanks!!!

You can use this site to check your answers W|A

Type laplace transform (f(x)) , or inverse laplace transform (f(s)) .
