It would be B because you would take amelias age and take two away since todd is five years younger to get the a-5.
hope this helps :)
If you nee solving it will be:
c^6(-3c^5)^2
c^6(3c^5)^2
c^6·3^2(c^5)^2
c^6·9(c^5)^2
c^6·9c^10
9c^6c^10
9c^6+10
9c^16
So the answer is:
9c^16
(9c to the power of 16)
Sorry I was late..
I'm assuming it is -m, +m, -m, +m etc..
