Question

If LM = X+3, MN = 2x, LN = 4x, and M is between L and N, then LN = ?​

Answer 1

LN = 12

Explanation:

If LM = X+3, MN = 2x, LN = 4x, and M is between L and N, then LN = 12.

Answer 2

LN = 12

Explanation:

L______M_____N

LM = x+3

MN = 2x

LN = 4x

M is the midpoint of LN

LN= ?

LM + MN = LN

x + 3 + 2x = 4x

x + 2x + 3 = 4x

3x + 3 = 4x

-3x -3x

----------------------

3 = 1x

/1 /1

----------------------

3 = x

LN = 4x

= 4 (3)

= 12

LN = 12
