Answer: 6
The remainder theorem says that if we divide p(x) over x-k, then the remainder is r = p(k)
In this case, we have p(x) = x^2+5 and x-k = x+1 = x-(-1). So k = -1 is plugged into p(x) to get
p(x) = x^2+5
p(-1) = (-1)^2+5
p(-1) = 1+5
p(-1) = 6
That is why the remainder is 6. You can use polynomial long division or synthetic division to confirm this answer.

Step-by-step explanation:
Answer:
See below
Step-by-s.ep explanation:
6. Let the 3 integers be k-2, k and k+2.
So k(k+2)-k(k-2) = 28
k^2 + 2k - k^2 + 2k = 28
4k = 28
k = 7.
So the 3 integers are 5, 7 and 9.
Answer: 7x - 6
Step-by-step explanation:
- Since you are not aware what the number's value is, use a variable, as 7x since 7 is multiplied by an unknown number. Then, subtract 7x - 6.
For the first one:tick the second to last.
for the second: tick the first circle.
for the third: tick the second to last.
for the forth: tick the second.
for the fifth: tick the last.
for the last one: tick the second.
Hope it helps...
