Multiply. give your answer in standard form. (3n2 + 2n + 4)(2n – 1) a. 6n3 + n2 + 6n – 4 b. 6n3 + 7n2 + 6n – 4 c. 6n3 – n2 + 10n – 4 d. 6n3 + n2 + 10n – 4

A

Step-by-step explanation:

(3n²+2n+4)(2n-1)

to solve this multiply through by using each term in one bracket to multiply all terms in the second bracket to open the bracket.

3n²(2n-1) + 2n(2n-1) +4(2n-1)

6n³-3n² +4n²-2n+8n-4

6n³+n²+6n-4

Hence the correct option is A

e) none of the above because the measure of angle cba is 101°
