Question

Points L, M, and N are collinear. Given LM = 13 and LN = 20, what is a possible value of MN?

A. 6
B. 7
C. 8
D. 9

Answer 1

Given that points L, M, and N are collinear, and distances LM equals 13 and LN equals 20, the distance MN must be 7 units since MN equals LN minus LM.

Step-by-step explanation:

If points L, M, and N are collinear and we know that LM = 13 and LN = 20, then we can conclude that point M must be somewhere between points L and N on that line. The distance MN will be the difference between LN and LM, which means MN = LN - LM. Given this, MN = 20 - 13, which equals 7. Thus, a possible value of MN is 7 units.
