33) A man Spend 3hr to walk from a
Point X to another point y 20/2 km
apart. If his return Journey took
4 hours, find his average speed
for the
entire Journey​

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

the first one, all those points on the line just make a strait line.

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!

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.
