I don't understand what to do here. Can someone please explain? Please show all of your steps in your answer.

Parallelogram PQRS is shown in the coordinate plane below. What is the perimeter of parallelogram PQRS?

42

Step-by-step explanation:

Opposite sides of a parallelogram are congruent

You need to find the distance between Q(6, 6) and R(1, -6) using the distance formula.  

PS = QR =

     =

PQ = SR = 8

Perimeter = 13 + 13 + 8 + 8 = 42

dont trust me im no expert these losers made me fail a test bro this sucks

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.
