Answer:
= 9y^4 -6y^3 -17y^2 -18y -10
Step-by-step explanation:
(3y^2 + 2y + 2) x (3y^2 – 4y – 5)
9y^4 - 12y^3 - 15y^2 + 6y^3 -8y^2 -10y +6y^2 -8y -10
= 9y^4 -6y^3 -17y^2 -18y -10
The answer to the equation is the second option.

Answer:
Answer 8: D
Answer 9: A
Step-by-step explanation:
8D: 5(12)/4-1=14
9A: Plug in -5(1)+2 = -3, so the point is (1,-3)
Question 10 is not visible
Multiply the numbers: 3 x 2=6 = 6x + 5 - 12x - 2 x 149x
Next Multiply the numbers 149 x 2 = 298
Then, Group like terms, =-6x-12x-298x+5
Add similar elements -6x-12x-298x=-316x,
and you get -316x+5!
