Answer:
scale factor = 3
Step-by-step explanation:
To determine the scale factor, calculate the ratio of the image x and y coordinates to the original x and y coordinates, that is
scale factor = 
= 
= 3
It is the commutative property of addition

Answer: Choice 2) sin(B) = cos(90-B)</h3>
Explanation:
The rule is that
sin(A) = cos(B)
if and only if A+B = 90.
Solving for A gets A = 90-B
So we end up with
sin(90-B) = cos(B)
which is the same as
cos(B) = sin(90-B)
These three roots are sufficient to enable us to form a 3rd degree polynomial:
f(x) = (x+4)(x-4)(x-2) = (x^2 - 16)(x-2) = x^3 - 2x^2 - 16x + 32 (answer)
