Answer:
Step-by-step explanation:
1) 9 x 4 = 36
9 + 4 = 13
2) 9 x -4 = -36
9 + (-4) = 5
3) 4 x3 = 12
4+ 3 = 7
4) -4 x 3 = -12
-4 + 3 = -1
Hi,
Have a good day.
#1 is -9
#2 is 3
-9x3 is -27 then add 10 to that you get -17
5x3 is 15 then subtract 1 and you get 14
603*.09=54.27 so add 603+54.27= 657.27
