Hi please show all working

uestion w (6 I-le). Find the components of.

a) v = ( 4 , 0 , -8) ; w = ( 6 , -1 , -4)

v - w =( 4 - 6 , 0 +1 , -8 +4) = ( -2 , 1 , -4)

b) -v +u = ( -4 , 0 , 8) + ( -3 , 1 , 2)

= ( -7 , 1 , 10)

c) - 3( v - 8w)

8w = ( 48, -8 , -32)

v - 8w = ( 4 , 0 , -8) - ( 48 , -8 , -32)

= ( -44 , 8 , 24)

-3( v -8w) = ( 132 , -24 , 72)
