Answer:

  -19, -18

Step-by-step explanation:

Let x represent the smaller integer. Then the larger is x+1 and their relationship is ...

  x +1 = 20 + 2x

  -19 = x . . . . . . . . . subtract x+20 from both sides.

The smaller integer is -19; the larger is -18.

pantera1 [17]

Answer:

The answer to your question is: The second option is correct

Step-by-step explanation:

Data

                         x³  +  4x²  -  43x  -  10 by  x-5

Synthetic division

                       1        4      -43       - 10             5

                                5        45         10

A fourth degree polynomial with real coefficients can have -4, 8i,+4i, and as its zeros. True or false? Justify your answer.
liraira [26]
You didn't give the fourth zero, but the answer is still false. If you have a root or an imaginary number as a zero, then its conjugate is also a zero. So if 8i is a zero, then -8i must also be a zero, and if 4i is a zero, then -4i must be a zero, with those zeros and -4, the number of zeroes exceeds the number of zeroes that a fourth degree polynomial can have.
