Suppose o is a randomly chosen point inside △abc. line segments

de, fg, and hi are drawn through point o such that de∥ ab, fg∥bc, and hi∥ ac. the areas of △foh, △eoi, △god are equal to a, b, and c, respectively. find the area of △abc in terms of a, b, and c.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
