the area of a rectangular raised garden bed for growing beets is given by the expression(3b)(3b-3). the length, l, of the mat is greater than its width, w.

based on the given information and the formula for area of a rectangle a=∫w, , which of the following statements must be true?

a
the coefficient of b is 3, meaning the length of the rectangle is three times its width.

b
(3b-3) is a factor in the expression and represents the length of the rectangle.

c
(3b-3) is a term in the expression and represents the width of the rectangle.

d
