Heather put 26 counting bears in a box. she gave 13 to jaclyn .write an expression to show how many cubes are left in the box

Step-by-step explanation:

The total bear = 26

Let the number giving out be x

Number left = 26 - x

So when 13 was given to Jaclyn

x = 13

Number left = 26 - ×

Number left = 26 - 13

Number left = 13

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.
