Answer 1

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
