Terry drives 20 miles at an average rate of 50 miles an hour while Sherry drives 30 miles an hour at an average rate of 40 miles per hour. Neither person stops. Terry needs M fewer minutes to complete the trip than Sherry does. What is the value of M?

step-by-step explanation:

what are the statements? and what do you mean by "216 2 1 6"?

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.
