Divide these polynomials.

(x4 - x3 - 7x2 + 4x - 3) (x - 3)

a. x3 - 3x2 + 2x + 2
b. x3 + 2x2 - x + 1
c. x3 - 2x2 - x + 1
d. x4 + 2x3 - x2 + x

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
