Answer:
LM = LN + MN [ assuming N is a point between L and M ]

then find MN:

Answer:
6
Step-by-step explanation:
the square root is basically exponents 6*6 is 6^2 which is 36.
You would multiply both and then the answer you would put into ratio form
Multiplicative inverse makes the numver 1 so it multiplies by 1 which cancles the number
examle
1/3x=10
to make 1/3 into 1
we multiplyu it by its mutlipcative invers which is 3/1
1/3 times 3/1=3/3=1
1/3x times 3/1=3/1 times 10
1x=30
additive inverse makes the number 0 to cancel it out
so example
x+3=10
add the inverse of 3 to make it 0
inverse of 3 is -3
3+-3=0
so x+3-3=10-3
x+0=7
x=7
