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

The fraction that names all of the oatmeal bar halves is
The fraction that names all of the oatmeal bar pieces obtained by cutting the the bar halves into two equal pieces is
Step-by-step explanation:
To answer the question, we note that there are 5 oatmeal bars, and since each bar is cut in half, we have the fraction that names all of the oatmeal bar halves is
If Lucy further cuts each part of the oatmeal bar into 2 equal pieces to share with friends, then the fraction that names all of the oatmeal bar pieces is
