Luis is making two batches of muffins for a school picnic. one batch of muffins uses 1/4 cup of oats and 1/3 cup of flour. what is the total number of cups of oats and flour needed for two batches? explain how you could use fraction strips to solve the problem.

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.
