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
the term -3 means that the width of the rectangle is 3 units less than its length.

Can someone factor this fully? my friend and i have two different answers and i would like to know if either of them is right. you in advance. a^2 - b^2 + 25 + 10a

Which expression is equivalent to 16 in exponential form? a) 4 × 4 b) 8 × 2 c) 23 d) 24

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
