Bode Plots with a undeclared variable?

Hi,

I've been given a transfer function of:
K / (1 +10s)(1+s)^2

Not that hard a function, but i've been asked to "draw the straight-line approximation to the Bode mag/phase plots of the open loop transfer function".

Any idea on how to do this? I semi understand Bode plots but I dont know how to put in K without knowing what it is? Later questions include K equaling something but this first one doesnt, thats why im stuck!

Any help? Cheers,
Tom
