Two resistors with values of 6.0 and 12 are connected in parallel. This combination is connected in series with a 6.0 resistor. What is the equivalent resistance of this combination?

This is what i found “in a gas turbine engine, the combustor or combustion chamber is fed high pressure air by the compression system. early gas turbine engines used a single chamber known as a can type combustor. today three main configurations exist: can, annular and cannular (also referred to as can-annular tubo-annular).” i hope this you for what your looking for. can you plz mark me brainliest?
