Answer:
The noun the underlined participle modifies is:
b. aspects.
Explanation:
In the sentence we are analyzing here, there is a present participle, "troubling". A present participle is formed by adding -ing to a verb stem (interesting, caring, loving, etc.). Present and past participles can function as adjectives, modifying nouns or pronouns in a sentence. That is precisely the case here, where "troubling" is modifying the noun "aspects", attributing a quality to it. For that reason, we can choose letter B as the best option.
B. to explain something
Because he explains about Flamenco dance.

That expression can be simplified by combining like terms.
Like terms are terms that have the same variable(s) and the same exponent(s).
The like terms are 7x and 9x.
You can combine like terms by adding the coefficients (the number in front of the exponent) together and then tacking on the variable at the end.
7x + 9x = 16x
Add 16x back to the term that can't be combined (-8y), and the simplified expression is 16x - 8y
