help mee

Answer 1

\(\left(-53\right)\cdot49+\left(-49\right)\cdot47\)

\(=49\left(-53-47\right)\)

\(=49\cdot\left(-100\right)\)

\(=-4900\)

Answer 2

(−53)⋅49+(−49)⋅47

(−53)⋅49+(−49)⋅4

=49(−53−47)=49(−53−47)

=49⋅(−100)=49⋅(−100)

=−4900

 

Answer 3

(-53).49+(-49).47

=(-53).49+49.(-1).47

=(-53).49+(-1).47

=(-53).(-1)+49.47

=53+49.47

=(53+47).49

=100.49

=4900
