Question

Simplify using suitable properties. Also mention the property used:

a) -194 X 143+ (-194) X 57

b) 256 X 373+256 X (-73)

c) 3219 X 81+3219 X 12+3219X 7

d) -2916 X 1005​

Answer 1

Step-by-step explanation:

a) reverse distributive property

-194×(143 + 57) = -38800

b) reverse distributive property

256×(373 - 73) = 76800

c) reverse distributive property

3219×(81 + 12 + 7) = 321900

d) distributive property

-2196×(1000 + 5) = -2196000 + (-2196)×5

= -2196000 - 10980

= -2206980
