Question 6(Multiple Choice Worth 1 points) (06.01 LC) Choose the correct classification of 5x + 2x2 − 8 by number of terms and by degree. A. Third degree polynomial B. Fourth degree trinomial C. Second degree trinomial D. Sixth degree polynomial

Question 7: Choose the correct simplification of the expression (3x − 6)(2x2 − 4x − 5)

7. 6x³ - 12x² + 12x + 15

Step-by-step explanation:

(3x-6)(2x² - 4x - 5)

3x • 2x² = 6x³

3x • -4x = -12x²

3x • -5 = -15

-6 • 2x² = -12x²

-6 • -4x = 24x

-6 • -5 = 30

combine terms

6x³ - 12x² - 15 - 12x² + 24x + 30

combine like terms

6x³ - 24x² + 24x + 15

hope this helps :)

in the future, only ask one question per submission. thanks!

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
