Given: m is the midpoint of ln; lm =8 prove: ln=16

I hope this helps

Step-by-step explanation:

M is the midpoint of LN                                         Given

LM≅LN                                                      Definition of Midpoint

LM=8                                                                       Given

MN=8                                                                  Substitution

LM+MN=LN                                          Segment Addition Postulate

8+8=LN                                                               Subsitution

LN=16                                                                     Addition

Option A and B are the correct answer.

Step-by-step explanation:

We have vector u has a magnitude of 5 units, and vector v has a magnitude of 4 units.

We need to find possible magnitude of u +v.

Consider u and v are in same direction, it will give maximum magnitude possible.

         u + v = 5 + 4 = 9, so 9 is the maximum magnitude.

Consider u and v are in opposite direction, it will give minimum magnitude possible.

         u + v = 5 - 4 = 1, so 1 is the minimum magnitude.

So magnitude of u + v lies in between 1 and 9.

Here option A, B lies in between A and B

Option A and B are the correct answer.
