Miguel and his brother Ario are both standing 3 meters from one side of a 25-meter pool when they decide to
race. Miguel offers Ario a head start. Miguel says he
will start when the ratio of Ario's completed meters to
Ario's remaining meters is 1:4.
O 4.4 meters
O 7.4 meters
O 17.6 meters
0 20.6 meters

step-by-step explanation:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

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.
