Best ResponseYou've already chosen the best response.1List the numbers the go into 6 and 12 obviously the GCF will be even since we are working with 2 even numbers :) 2,4,6, <our GCF GCF=6 :)

Best ResponseYou've already chosen the best response.1you can also go through the options and check each one example: for choice A, we have 6(a + 6) distribute the outer 6 through to get 6(a + 6) = 6*a + 6*6 = 6a + 36

Best ResponseYou've already chosen the best response.16a + 36 is not the same as 6a + 12, so choice A is ruled out. Check the others the same way.
