∆JKL~∆MNO and J/K MN =2/3 find the length of NO if KL=12.
Gre4nikov [31]

Answer:

Therefore the length of NO is 18 units.

Step-by-step explanation:

Given:

∆JKL~∆MNO and

\dfrac{JK}{MN}=\dfrac{2}{3}

KL = 12.

To Find :

the length of NO = ?

Solution:

Δ JKL ~ Δ LMN ….{Given)

If two triangles are similar then their sides are in proportion.  

\dfrac{JK}{MN} =\dfrac{KL}{NO}=\dfrac{JL}{MO} \textrm{corresponding sides of similar triangles are in proportion}\\  

Substituting the values we get

\dfrac{2}{3} =\dfrac{12}{NO}\\\\NO=\dfrac{36}{2}=18\\\\NO=18\ unit

Therefore the length of NO is 18 units.

4/3x+ 4 2/3 equivalent to
Dominik [7]
I believe this question should be a multiple choice question as there are numerous solutions.

Some of these solutions are:
4/3x+ 4 2/3 = <span>4/3x+ 8/3
</span>4/3x+ 4 2/3 = <span>8/6x+ 4 4/6  
</span>4/3x+ 4 2/3 = 12/9x + 4 2/3 

This can be explained as:
For 8/6x+ 4 4/6, divide the numerator by 2 and the denominator by 2 in each of the terms, the output will be the original expression.

For 12/9x + 4 2/3 , divide the numerator by 3 and the denominator by 3 in the first term (12/9x), the result will be the original expression.
