The length of a rectangle is 3 inches greater than the width write a polynomial that represents the area of the rectangle

Suppose the length is x, the width is then (x-3), the area is x(x-3)
expand it: x²-3x, which is the polynomial you are looking for.

or you can suppose the width is x, the length is then (x+3), the polynomial is x²+3x

When two lines intersect, they form two pairs of equal angles, which, taking one of each, add up to 180°. (jargon: angles forming a straight line   show more
