Arectangular wall has a length of 12ft and a width of 8ft. the wall has two rectangular windows. each window has a width of 3ft and a height of 5ft. andrea chooses a point on the wall at random to test a new paint color. what is the probability she could choose a point on a window

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
