By the commutative property of addition, the answer you got
c = -b+5a
is identical to selection ...
D. c=5a-b
The commutative property tells you the order of addition doesn't matter, so
(-b)+(5a) = (5a)+(-b) = 5a-b
(This is one of the reasons we study these properties.)

Hello :
the polar form is : z = |z
|×e^(iθ)
z=-10+8i
|z | =√((-10)²+(8)²) =<span>√(164)
cos</span>θ = -10/√(164)
sinθ = 8/√(164)
find θ by arctan(8/-10)
