WILL MARK BRAINIST FOR THE CORRECT ANSWER Let f(x) = 9x3 + 21x2 − 14 and g(x) = 3x + 1. Find f of x over g of x.

a) 3 times x squared plus 6 times x minus 2 minus 12 over the quantity 3 times x plus 1
b) 3 times x squared plus 6 times x minus 2 plus 12 over the quantity 3 times x plus 1
c) 3 times x squared plus 6 times x plus 2 minus 12 over the quantity 3 times x plus 1
d) 3 times x squared plus 6 times x plus 2 plus 12 over the quantity 3 times x plus 1

When constructing a perpendicular line through a point off a line, how can you verify that the lines constructed are perpendicular? check the angles used in the construction with a straightedge to ensure consistency. check the distance along the lines at several places with a compass to ensure they are the same length. check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles. check the distance between the lines at several places with a compass to ensure they are equidistant. question 2(multiple choice worth 1 points) (01.03 lc) which of the following steps is included in the construction of a perpendicular line through a point on a line? connect arcs that are above and below the given line with a straightedge. connect arcs that are above the original line with a straightedge. create arcs on either side of a point that is off the given line. create a copied angle by using the first two lines as the original angle.
