The complex number is given as: 2-8i
So for conjugate, you just flip the sign of the imaginary part:
2+8i will be the answer
(1) C and (2) D
(1)
distribute the left side of the equation
2h - 16 - h = h - 16 ( simplify left side )
h - 16 = h - 16
Since both sides are equal, any value of h will make the equation true.
Hence there are infinitely many solutions to the equation → C
(2)
3 + 6z = 13 + 6z ( subtract 6z from both sides )
3 = 13 ← not possible
Hence there are no solutions to the equation → D

The associative property of addition is being demonstrated here. The parenthesis are moved around to "associate" or "group" the values into two different pairs.
Note: the associative property of multiplication is very similar and it is
a*(b*c) = (a*b)*c<span />
