Step-by-step explanation:
1) (-9)×6+(-9)×4
-54+(-36)
-54-36
= -90
2) 30×(-22)+30×(14)
-660+420
= -240
3) 43×(-33)+43×(-17)
-1419+(-731)
= -2150
4) (-27)×(-16)+(-27)×(-14)
432+378
= 810
5) 8×(-12)+7×(-12)
-96+(-84)
= -180
6) (-15)×(-14)+(-15)×(-6)
210+90
= 300
7) (-36)×72+(-36)×28
-2592+(-1008)
= -3600
