What is a simpler form of the expression?

(2n2 + 5n + 3)(4n - 5)

a. 8n^3 + 10n² - 13 n - 15
b. 8n^3 + 30n² - 37n - 15
c. 8n^3 - 10n² + 37n - 15
d. 8n^3+ 13n² - 10n -15

answerthe vertex form

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
