Rewrite 89 and 1921 so that they have a common denominator.
Then, use <, =, or > to order 89 and 1921.

89/1    1921/1    89/1 < 1921/1

Step-by-step explanation:

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

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.
