Answer:
LN = 66 cm
Step-by-step explanation:
The 3 parallel lines divide the 2 sides they intersect in proportion, that is
=
, substitute values
=
( cross- multiply )
15LM = 315 ( divide both sides by 15 )
LM = 21
Hence
LN = LM + MN = 21 + 45 = 66 cm
-5.8 + (-2.5) = -8.3
since both the number are negative you simply add the numbers and use the negative sign.

The answer to 20 divided by 70 is
0.2857
The initial value is 3. The common ratio is -9/3 = -3. The general formula is
.. an = a1*r^(n-1)
So, for your values, ...
.. an = 3*(-3)^(n -1)
