Answer:
c. both
Step-by-step explanation:
Just sub x in with 5.
So 6(5)^3+8(5) = 6 (125) + 40 = 750 + 40 = 790.
So 790
Answer:
-3x^2-21x+24
Step-by-step explanation:
Kindly separate the answer choices: (x - 4), (x + 1), (x + 4) , (x - 1). The trinomial is thus -3x^2-21x+24, which can be factored as follows: -3(x^2 + 7x - 8)
Then we have -3x^2-21x+24 = -3(x^2 + 7x - 8), which factors further into:
-3(x + 8)(x -1) and so we conclude that the only binomial that is a factor of
-3x^2-21x+24 is (x - 1).
If one angle is 80 degrees we can assume that each other angle must be 80, 100, and 100 degrees.
