The transfer function of system $1$ is $G(s)$ and the transfer function of system $2$ is $H(s),$

Find the following:

$G(s)=\frac{s+10}{s^3+6s^2+9s+10}$

$H(s)=\frac{s+1}{s+2}$

A$.$ The transfer function of the series configuration of sys $1$ and sys $2$

B$.$ The transfer function of the parallel configuration of sys $1$ and sys $2$

C$.$ The transfer function of the series configuration of sys $1$ and sys $2$ and unity

feedback.

D$.$ The transfer function of the non$-$ unity feedback where sys $2$ in feedback path.
