Mr Green:
4(3a+1+2b) = 12a + 4 + 8b

Mrs Green:
6(5a-a)+4(2+4b)=6*4a + 8 + 16b = 24a +16b + 8

Keith:
4(2+4b+6a) = 8 + 16b + 24a=24a+16b + 8

Kevin:
4(6a+2)+8b + 2 = 24a + 8 + 8b + 2 = 24a + 8b + 10

Thus Mrs Green and Keith has the expression that is equivalent to

'24a + 16b + 8'

Hope that helps!
