What is the remainder when x^6-4x^4+4x^2-10 is divided by x+3

  431

Step-by-step explanation:

When polynomial f(x) is divided by x-a, the remainder is f(a). Here, "a" is -3. We can compute f(-3) as ...

  f(x) = ((x^2 -4)x^2 +4)x^2 -10 . . . . Horner form simplifies evaluation

  f(-3) = ((9 -4)9 +4)9 -10 = 431

The remainder of the division is 431.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

my answer is$ 12

step-by-step explanation:

because 15 -2=12
