We simplify the equation to the form, which is simple to understand
5(3+k)=45

Reorder the terms in parentheses
+(+15+5k)=45

Remove unnecessary parentheses
+15+5k=+45

We move all terms containing k to the left and all other terms to the right.
+5k=+45-15

We simplify left and right side of the equation.
+5k=+30

We divide both sides of the equation by 5 to get k.
k=6

Sergeeva-Olga [200]

Answer:

centre of the circle(h,k)=(5,2)

radius(r)=10

Step-by-step explanation:

Now,

equation of the circle is giveb by (x-h)^2+(y-k)^2=r^2

or,(x-5)^2+(y-2)^2=(10)^2

or,x^2-10x+25+y^2-4y+4=100

or,x^2+y^2-10x-4y+29-100=0

or,x^2+y^2-10x-4y-71=0
