Answer:

Step-by-step explanation:
The equation of a circle with center (a,b) and radius r, is

From the question, the center of the circle is located at (-6,2) and the radius is

We substitute the center and radius to get:

Simplify to obtain:

x^2 - 2x = 146
x^2 - 2x - 146 = 0
See attachment. The quadratic formula is needed in this case.

Answer:
7/100
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 70 and 100 is 10
Divide both the numerator and denominator by the GCD
70 ÷ 10
100 ÷ 10
Reduced fraction:
7
10
Therefore, 70/100 simplified to lowest terms is 7/10.
