Answer:
20
Step-by-step explanation:
17+24+26+13=80 divided by how many numbers there are 80 divided by 4 = 20.
The first term is 5. The sequence goes by 2. And 23 is the 9th term. 9x2=18
23-18=5
Consider this solution, if it is possible, check the result:
1) if to divide polynomial 'x³-3x²-6x+8' on 'x+2' result is: x²-5x+4, then x³-3x²-6x+8=(x+2)(x²-5x+4);
2) x²-5x+4=(x-1)(x-4), then
3) x³-3x²-6x+8=(x+2)(x-1)(x-4).
4) zeros are: -2;1;4. Other zeros are: 1 and 4.
Answer: 1;4.
The final expression in standard form will be 1.601 * 10^9
