Dimensions: x by 3x by x3 area of base = x(3x) = 3x2 box 2: dimensions: x by 4x – 1 by x3 area of base = x(4x – 1) = 4x2 – x complete the statements about the number of terms in the polynomial representing the volume of each box.

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
