Kristin is planning to visit four cities A, B, C, and D. The table to the right shows the time ( in hours) that it takes to travel by car between any two cities. Find an optimal
tour using the brute-force algorithm. Choose the correct answer below.

Last option is

G) all of the routes are of equal distance

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.

the answer should be a. snail
