Question

one edge of a painting is 6 inches. longer than the shorter edge. the picture has a 2 inch wide frame. write a quadratic function “f” in standard form to represent the total area of the picture and frame. then find the total area of the framed picture of its shorter edge is 8 inches long.

Answer 1

'One edge of a painting is 6 in: longer than the shorter edge. The picture has a 2-in:-wide frame: There is one rectangle inside the other rectangle: The distance between two edges of two rectangles is 2. The length of the rectangle is X + 6 and width is x The portion between two rectangles is shaded: Part A Which quadratic function represents the total area of the picture and frame? A. f(x) = x2 + 8x + 12 B. f(x) = x2 + 1Ox + 24 C. f(x) x2 + 12x + 32 D. f(x) = x2 + 14x + 40 Part B What is the total area of the framed picture if its shorter edge is 8 inches long? Enter your answer in the box: in.2'
