In the figure, CDEF is a rectangle and ABE and BCF are triangles. AB = 24 cm, AE = 18 cm, DC = 20 cm, EB = 30 cm and
ZBAE = ZBFC = 90°. Find the area of the figure,

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
