Answer:

R_eq=35.425 ohm

Explanation:

If we want to find the equivalent resistance across the output terminals, we know that all the resistors will be considered and battery's internal resistance will be added instead of battery.

[tex]R_{10||7}={10*7}/{107}=70/17[/tex]

then

R_e1= [tex]R_{10||7}+R20=410/17[/tex]=24.12

and then

R_e2={24.12}//{24.12+7}=5.425

and finally

R_e=5.24+30=35.425
