Answer:
s= -1
Step-by-step explanation:
Using the quadratic equation we get:

Factoring out 2 we get

Factoring out the imaginary number:

So b.
It is a reflection across the y axis, then a translation to the right 2 units.

Answer:
C = 14 pi inches
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
49 pi = pi r^2
Divide each side by pi
49 pi/pi = pi /pi r^2
49 = r^2
Take the square root of each side
7 = r
The circumference is given by
C = 2 * pi *r
C = 2 * pi *7
C = 14 pi inches
