There are one subordinate clasuses
Any two negative numbers will always give you a positive number, so let's just ignore the - for now.
Straight away, two numbers that multiply to give 72 is 8 and 9. This is just basic multiplying. Now, to check if it adds to 17 (because we're ignoring the minus for now), you just do 8 + 9, which coincidentally happens to be 17. So you just place a minus in front of 8, and a minus in front of 9, and you get -8 × -9 = 72, and -8 + -9 = -17.
The purpose of this speech is to illustrate Juliet’s love for Romeo in spite of his family name.
In these lines she talks about the meaning of names. She says that names should not and do not define what something is. She uses the rose for comparison. A rose could be named skunk or bicycle. However, changing the name does not change the actual rose. It will still smell sweet and be beautiful. She says that she would love Romeo no matter what his name was.
A funny image, and adding sound effects to a slide.
The original sentence used the pronoun in a wrong way - the way that sentence is written, it would seem that the table needed washing, and not the dishes. The revised sentence fixes this mistake by placing the pronoun nearer the antecedent.
An antecedent is a word or a phrase which is located in front of the pronoun (ante means before) and which that pronoun refers to. The pronoun here is 'that,' and its antecedent is 'the dishes.' So by moving the pronoun 'that' nearer the antecedent 'the dishes' we fixed the ambiguous sentence.
