Yeah, i’ve tried to do this problem and still have no clue can anyone me out maybe? and maybe explain how you got your answer too, so i can get it

Your answer is 70.

As this is a parallelogram, lines PN and MO are the same length. This also means K is the midpoint of line PN. From this, you can deduce that PK = KN as both are half of line PN

So, equating the expressions gives

And now we have to rearrange and solve for x by factorising

Now, if we substitute both values into PK =5x, we know that x cannot be - 2, as we cannot have a negative length.

Using x = 7 and substituting

Then multiplying by 2 to give the entire length of PN

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
