I don’t know what we have to do but from what I think it is.. to me the answer for the first one is 5(3)+9(-2)=-3. The way I figured this one out is I multiplied 5x3 which gave me 15 and then 9x-2 which gave me -18. Once you have that you should subtract 15 and -18 which will give you -3. I don’t know the second one... sorry
