13. A projector displays a rectangular image on a wall. The height of the wall is x feet. The area (in square feet) of the projection is represented by x2 - 12x + 32. The width of the projection is (x-4) feet. a. Write a binomial that represents the height of the projection.

step-by-step explanation:

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

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.
