A.9×(11+19)=(9×11)+(9×19)=99+171
=270
b.(13×88)-(13×62)=1144-806
=338
c. ((-34)×17)+((-34)×(-21))
=(-678)+714=36
d. (5×133)-(5×33)=665-165=500
e. (49×(-13))+(49×213)
=(-637)+10437=9800
f. (28×(-125))-(28×25)
=(-3500)-700=-2800
g.((-33)×(-616))+((-33)×(-16))
=20328+528=20856
h. (125×(-278))-(125×(-268))
=(-34.750)-(-33.500)
=68.250
i.(42×1579)-(42×1208)
=66.318-50.736=15.582
j. ((-39×(-3526)+((-39)×3017)
=137.514+(-117.663)=19.851.
