94

Step-by-step explanation:

3mm and 4mm and 5mm

This not the the traditional way but its pretty easy way to do it!

3 x 4 = 12

3 x 5  = 15

5 x 4 = 20

but before you add them up remember there are two of each so multiply all of them by 2

12 x 2 = 24

15 x 2 = 30

20 x 2 = 40

and now just add them up!

24 + 30 = 54

54 + 40 = 94

the reason i like this method is because all you have .to put on your paper is

12 ,15, 20

then you multiply by 2

and write 24, 30 ,40

and add them up! no weird formulas or any thing just simple logic

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.
