Kitty [74]
Base on my research there are ways to get the number of roots. If you are looking for negative roots and even the positive one has their own ways. But in this problem, we just need to determine the total number of roots of a polynomial. In determining the total number of roots, you just need to find the degree of the polynomial function. The degree refers to the highest exponent of the polynomial. Therefore, in the function given, 6 is the degree of the polynomial function. The total number of roots is 6.

Determine whether the sequence is arithmetic, geometric, or neither, and justify your response.
Kobotan [32]

9514 1404 393

Answer:

  geometric

Step-by-step explanation:

The signs of the terms alternate, so it cannot be an arithmetic sequence.

The ratios of terms are ...

  6/-3 = -12/6 = 24/-12 = -2

The terms have a constant ratio of -2, so the sequence is geometric.

iren [92.7K]

Answer:

all the values

Step-by-step explanation:

-8(-x-5)=40+8x\\\\-x-5=\frac{40}{-8}+ \frac{8x}{-8} \\\\-x-5=-5-x\\\\-x-5=-x-5\\\\-x=-x-5+5\\\\-x=-x+0\\\\-x=-x\\

-1(-x)=-1(-x)\\\\x=x

so all the values for x are solutions
