Step-by-step explanation:

Find the amount of car each person sold per year:

Ronaldo:

104 cars / 2 years

= 52 cars per year

Maria:

322 cars / 7 years

= 46 cars per year

Bruno:

516 cars / 12 years

= 43 cars per year

Ronaldo sold the most cars (52) per year.

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.
