Andrew can run the forty yard dash in 1/2 the time that Brett can. If the sum of the two boys' times is 16.2 seconds, how many seconds does it take Brett to run the forty yard dash?

is only a line? i think so

answer: i literally just answered this question but they want me to do it again

step-by-step explanation:

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.

3 qrs + 3/2 xy hope this : /
