Answer 2

Hii @udhavsasane000 ,

Answer:

D = - 52

Step-by-step explanation:

D = 2 -1 3

1 3 -4

5 -5 4

= 2 [ ( 3 * 4 ) - ( -4 * -5 ) ] - ( - 1 ) [ ( 1 * 4 ) - ( -4 * 5 ) ] + 3 [ ( 1 * -5 ) - ( 3 * 5 ) ]

= 2 ( 12 - 20 ) + 1 ( 4 + 20 ) + 3 ( -5 - 15 )

= 2 ( -8 ) + 1 ( 24 ) + 3 ( -20 )

= -16 + 24 - 60

= 24 - 76

= - 52

D = -52
