Idk about b but for c, you just show distribution method and do 3m times 2m (which equals 6m squared) and then 3m times -1 (=-3m) and then 7 times 2m is 14m and then7 times -1 is -7. OKAY so now that u have all that, you have: 6m^2-3m+14m-7. Now collect like terms. You end up getting 6m^2+11m-7 AND THATS YOUR ANSWER !!!
