Quadrilateral DEFG - quadrilateral KLMN. Find the given side length.

Step-by-step explanation:

By the diagram FG = MN.

3y + 3 = 5y - 25          Add 25 to both sides

3y + 3 + 25 = 5y         Subtract 3y from both sides

28 = 5y - 3y                Combine

28 = 2y                       Divide by 2

28/2 = 2y/2

y = 15

15 is not your answer. It is just the value of y.

3y + 3 = 3*15 + 3 = 45 + 3 = 48

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.

the radius is 2 times the diameter.
