I don't know how to introduce the block (s+6) in simulink

I have the following block diagram I want to enter into Simulink, but I am having trouble as I do not know a way to enter the (s+6) block. I do not seem to find a way to do it with a transfer function as it is required that the numerator and denominator have the same degree.

Hi Carlos,
One option would be to use block diagram manipulation. For example (there is at least one other approach):
a) change the s+6 in the feedback path to 1
b) change 1/(s^2+9) to (s+6)/(s^2+9)
c) change 12 to 12/(s+6)
d) add 1/(s+6) on the line for Y(s) to right of the node that branches off for the feedback signal; Y(s) is now the output of this added transfer function
That should give you the same closed-loop transfer function Y(s)/R(s). Are there other transfer functions of interest?
