If the area of a rectangle is 6x^2 - x -15. If the length is 2x + 3, find the width.

Identify this conic section. x2 - y2 = 16 o line circle ellipse parabola hyperbola

Answer this two poles, ab and ed, are fixed to the ground with the of ropes ac and ec, as shown: two right triangles abc and edc have a common vertex c. angle abc and edc are right angles. ab is labeled 13 feet, ac is labeled 15 feet, ec is labeled 10 feet, and ed is labeled 4 feet.what is the approximate distance, in feet, between the two poles? 11.14 feet16.65 feet14.35 feet15.59 feet

How is this equation completed? i cannot find any examples in the book.
