Ed and Sana run at constant speeds. Ed can run 1 mile in 9 minutes, and Sana can run 3 miles in 45 minutes. Ed and Sana have the same starting point and run in the same direction, but Ed starts running 36 minutes after Sana,

the equivalent expression are always the hardest ones but you look at the gcf also

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.

answer: your answer is c
