Alex's friend pablo comes up with an exact equation to find out how many bags he needs. use his equation
to find out how many bags will actually be needed if b = x(2x+7)+3(2x+7)+(x+4) (2x +7), where the
quantity (2x + 7) equals 4. show how you arrive at your answer.

the answer is c

hope this !

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.
