Answer:

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

$x_{vertex}$ = $\frac{6-12}{2}$ = $\frac{-6}{2}$ = - 3

Thus the x- coordinate of the vertex is x = - 3 → B

The external angle of a regular polygon is 200 . How many sides does it have ? What is the measure of each interior angle? What

Zanzabum

Answer:

An 18 sided shape.

Since the sum of the exterior angles of a polygon is 360° and an angle of the regular polygon is 20°, then 360° / 20° is the number of sides. We find the answer = 18, an octadecagon
