So basically on this app you ask and answer questions. For example if you need help with a homework question you can type it in or take a picture of it and submit it and others will help answer it for you. You can also answer questions to help other people and that will help you earn points. When you ask questions however it requires you have points so remember to help other people too! Once you reach a certain amount of points you level up. Hope this helps

On this app, you can answer other people’s questions and even ask your own. You need points to ask your own though. To get points, you need to answer more questions. Each question varies on points depending on what the person has set the amount of points to be given to the person who answers. Hope this helps!!

Answer:

\huge\boxed{Center = (3,3),Radius = 2\sqrt{15} }

Step-by-step explanation:

<u><em>Given equation is</em></u>

x^2 + y^2 -6x-6y -42 = 0

Adding 42 to both sides

x^2 + y^2 -6x-6y = 42\\

Completing squares

x^2 -6x+y^2 -6x = 42\\(x)^2 - 2(x)(3) +y^2 - 2(y)(3) = 42

Adding (3)² => 9 and (3)² => 9 to both sides

(x-3)^2+(y-3)^2 = 42+9+9\\(x-3)^2 + (y-3)^2 = 60\\(x-3)^2  (y-3)^2 = (2{\sqrt{15})^2}

Comparing it with (x-h)^2+(y-k)^2 = r^2 where Center = (h,k) and Radius = r

We get:

Center = (3,3)

Radius = 2\sqrt{15}
