Christie was on a road trip. she traveled 320.95 miles on day one, 231.45 miles on day two, and 120.32 miles on day three. how many miles did she travel during her three-day trip?

Step-by-step explanation:

Given : Christie was on a road trip. She traveled 320.95 miles on day one, 231.45 miles on day two, and 120.32 miles on day three.

Then to find the total  number of miles she traveled during her three-day trip we need to add them all.

The number of miles she traveled during her three-day trip will be :_

Therefore, the  number of miles she traveled during her three-day trip  =

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.
