If you put the -6 in the x and than the -2 in the y the x it would be (-6+6)=0 and times that one more time it gives u 0 and than 2•0=0 so 0-2=-2 hopefully I helped
C.) 30 since they both have 5's just take them out then subtract 50 and 20 *but make sure u take out the decimal though* so after u subtract u will get 30 then line it up and put the decimal back then it will be .30
