Answer:

$Center = \boxed{1}, \: \boxed{ - 2} \: ; \: Radius = \boxed{3}$

Step-by-step explanation:

${x}^{2} + {y}^{2} - 2x + 4y - 4 = 0 \\ \\ ({x}^{2} - 2x + 1 - 1) + ( {y}^{2} + 4y + 4 - 4) - 4 = 0 \\ \\ ( {x}^{2} - 2x + 1) + ( {y}^{2} + 4y + 4) - 9 = 0 \\ \\ {(x - 1)}^{2} + {(y + 2)}^{2} = 9 \\ \\ {(x - 1)}^{2} + {(y + 2)}^{2} = {3}^{2} \\ \\ equating \: it \: with \\ \\ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ \\ h = 1 \\ k = - 2 \\ r = 3 \\ \\ center = \boxed{1} \: \boxed{ - 2} \: \: radius = \boxed{3}$

When the factor of a trinomial are (X+P) and (x+q) then coefficient of the x-term in the trinomial is A The sum of p and q B the

Marianna [84]

The answer should be A, the sum of p and q.

Plug in a value for p and q to figure this out.
Here, I'm using 4 for p and 5 for q.

(x+4)(x+5)
x^2+5x+4x+20
x^2+9x+20

Here, the coefficient for the x term is 9 and 9 is the sum of p and q (4+5).
