Answer 2

Hello Friend !!!

a. 19 x ( -13 ) + 19 x ( -7 )
    = 19 ( -13 - 7 )
    = 19 x ( -20 )
    = -380 ( Ans )
b. ( -517 ) x 9 + ( -517 )
   = -517 ( 9 + 1 )
   = -517 x 10
   = -5170 ( Ans )
c. ( -700 ) x 49 + ( -700 )
= -700 ( 49 + 1 )
= -700 x 50
= -35,000 ( Ans )
d. -2478 x 96 = ( -2478 ) x 4 
= -2478 ( 96 + 4 )
= -2478 x 100
= -247800 ( Ans ) 
e. ( -3989 ) x 8 + 3989 x ( -92 )
= ( -3989 ) x 8 - ( -3989 ) x ( -92 )
= -3989 [ 8 - ( -92 ) ]
= -3989 x 100
= -398900 ( Ans )
