I'd say its D but im not quite sure, its what makes most sense to me.
2(x + y) or 2y+x or 2x(x + y)
Answer is (a)
its a binomial
not a monomial
No work free points ;) thx
Answer:

Step-by-step explanation:
y = x² - 10x + 27
y = ax² + bx + c
This is the general form of the equation for a parabola.
We must convert it to the vertex form
y = (x - h)² + k, where (h,k) are the coordinates of the vertex.
We can do this by completing the square.
The figure below shows that your parabola has its vertex at (5,2).
