A bedroom wall is to be painted around a window as shown below. A rectangle with length 11 feet and width 10 feet. A smaller rectangle with length 3 feet and width 2 feet is cut out of the larger rectangle. What is the area of the wall that will be painted? 6 feet squared 104 feet squared 110 feet squared 116 feet squared

104 ft Squared

Step-by-step explanation:

You are taking away the room area. So 11x10=110 (Area of the whole wall) and you are cutting off 3x2=6 (Area of the wall you are cutting off). So you subtract 110-6= 104 ft2.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

55/i dont know i do it for the points
