Express as a trinomial: (2x – 3)(x + 7)

Answers

Answer 1
Answer: (2x-3)(x+7)=
2x^2 + 14x - 3x - 21=
2x^2+11x-21.
Answer 2
Answer:

Final answer:

To express the expression (2x – 3)(x + 7) as a trinomial, we distribute each term in the first bracket to the terms of the second. The result is 2x² + 14x - 3x - 21. After combining like terms, we find that the trinomial form is 2x² + 11x - 21.

Explanation:

The question asks to express the expression (2x – 3)(x + 7) as a trinomial. To do this, we use the distributive property of multiplication over addition, which states that a(b+c) = ab + ac. Applying this rule to the expression gives:

2x(x) + 2x(7) - 3(x) - 3(7)

Parsing this out leads to:

2x² + 14x - 3x - 21

Finally, we combine like terms:

2x² + 11x - 21

Thus, the trinomial form of the expression (2x – 3)(x + 7) is 2x² + 11x - 21.

Dante the Pilgrim is characterized by allusions to Aeneas and the Apostle Paul because _____.a. he wishes to be associated with key Biblical figures
b. he desires to highlight his virtuous actions by comparing them to those who were not virtuous
c. he wants to be ranked among the greatest writers of the Western world
d. he seeks to link himself with those who have taken similar journeys

Answers

The correct answer to the question that is being presented above would be letter D. The sentence 'He seeks to link himself with those who have taken similar journeys' was the reason why Dante the Pilgrim is characterized by allusions to Aeneas and the Apostle Paul.

Answer:

d. he seeks to link himself with those who have taken similar journeys

Explanation:

The Divine Comedy is an epic poem written by the author Dante Alighieri (1265-1321) is a classic of world literature written during the Renaissance.  The protagonist of the poem is the poet himself Dante Alighieri who travels between three completely different instances: Hell, Purgatory and Paradise.

The poem is an allegorical narrative, that is, the author describes situations that should not be interpreted only by their literal meaning. Therefore, the character Dante, the pilgrim, may also have symbolic representation. The story can be a kind of dream (he says it was sleep, a nap that took him to the jungle). Scholars of Dante's work say that the Dante of history is characterized as an allusion to Aeneas and to the apostle Paul because they all took long journeys and found themselves lost and hopeless somewhere along the way.
