Cody is painting the front door of his house. the dimensions of the door are 80 inches by 36 inches by 2 inches. if he paints all of the surfaces, how much area will he paint? explain

Sorry have no idea.

Step-by-step explanation:

SA= 2lh+2lw+2hw

SA= 2(80·36) + 2(80·2) + 2(36·2)

SA= 5,760 + 320 + 144

SA= 6,224in

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.
