The sum of five consecutive integers is five. What is the product of the five integers?
nadya68 [22]

Answer:Let n = the smallest integer

Then the other integers are n+1, n+2, n+3 and n+4

Sum = n + n+1 + n+2 + n+3 + n+4 = 5n + 10 = 5(n + 2)

So the sum is always divisible by 5, for any value of n

Which theorem equates the value of a polynomial at a given value ,k, to the value of the synthetic division of the polynomial by
Nimfa-mama [501]

Answer:

The remainder theorem

Step-by-step explanation:

The remainder theorem states that given a polynomial f(x) and a linear factor x - k as in the question, then if f(x) is divided by x - k, then remainder is obtained at the value of x - k = 0 ⇒ x = k. That is, the remainder is f(k) when x = k.

For example, if we have a polynomial f(x) = x³ + 3x² -2x + 1 and a linear factor x - 1. The remainder theorem states that the remainder when f(x) is divided by x - 1 is obtained by equating the factor to zero and finding the value of x.

So, x - 1 = 0 ⇒ x = 1

Substituting x = 1 into f(x), we have

f(x) = x³ + 3x² -2x + 1

f(1) = 1³ + 3(1)² -2(1) + 1

= 1 + 3 - 2 + 1

= 3.

So, the remainder is 3.
