The formula for this is

. Filling in accordingly,

. This simplifies to

and 36=6x. Therefore, x = 6 so the bases are 6 and 12.
The answer will end up being c
Answer:
79665
Step-by-step explanation:
26555 + 26555 is 53110 then add 26555 again at it equals 79665

138÷23 would equal 6,
therefore m would equal six
to check it substitute m for 6 and you should get 138!
