Answer:
6
Step-by-step explanation:
You need to divide it.Then you get 18 divided by 3.Which is 6
Answer:
B
Step-by-step explanation:
The vertex is the turning point of the parabola.
First find the zeros by equating y to zero, that is
(x - 6)(x + 12) = 0
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 12 = 0 ⇒ x = - 12
The vertex lies on the axis of symmetry which is situated at the midpoint of the zeros, thus
= = = - 3
Thus the x- coordinate of the vertex is x = - 3 → B
