(3 x 3) + (8 x 2) = ?
Using the order of operations you do what is inside the parentheses first, so multiplying the numbers, and then you add the products together.

Find an equation of the circle that satisfies the stated conditions. (Give your answer in standard notation.)

Alina [70]

$(x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2
\\---------------------------\\
\qquad center\ ({{ h}},{{ k}})\qquad
radius={{ r}}
\\ \quad \\
\textit{we know the center}\implies center\ ({{ 6}},{{ 8}})
\\ \quad \\
\textit{what's the radius "r"?}
\\ \quad \\
\textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
Center&({{ 6}}\quad ,&{{ 8}})\quad 
% (c,d)
P&({{ 4}}\quad ,&{{ 1}})
\end{array}\qquad 
% distance value
r= \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}$

find "r", then plug it in the circle's equation
