Find the radius of a circle with the equation:
x2 + y2 – 18x – 14y + 124 = 0

The radius of is .

Step-by-step explanation:

The given expression must be converted into the standard form of a circle, which is described by:

Where:

, - Location of center, dimensionless.

- Radius, dimensionless.

The expression is modified algebraically as follows:

1) Given

2) Commutative and associative properties.

3) Commutative and associative properties/Compatibility with addition

4) Perfect square binomial/Definition of sum

5) Compatibility with addition/Existence of additive inverse/Modulative property/Result

Given that , the radius of the circle is .

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

(3x-8) or (3x+8)
