Is KM||JN? Explain your reasoning.

Given:

JK = 10, LK = 18, MN = 15 and LM = 24

To find:

The segment KM is parallel to JN or not.

Solution:

Converse of the triangle proportionality theorem:

If a line divides two sides of a triangle proportionally, then it is parallel to the third side.

Cancel the common factors, we get

Similarly,

Cancel the common factors, we get

Therefore KM is not parallel to JN.

the solution is 12x-6y

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
