i spent 22 dollars on school supplies and the pencil box cost 2 dollars less than the notebook and the pens cost 3 times more than the pencils find a variable and describe it and for a algebraic equation and solve it

1 1/5

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.

the answer is

d.

5.3066 m2
