Answer: A
Step-by-step explanation:
(3x+2) (x-7)
FOIL
first 3x*x = 3x^2
outer 3x*-7 = -21x
inner = 2*x = 2x
last 2*-7 = -14
add them together = 3x^2 -21x+2x -14
combine like terms 3x^2 -19x -14
All the edges of a cube are the same length.
Volume = length x width x height
Volume = 9in x 9in x 9in = 729 in³
