Plz will give brainliest need asap \which statements are true about the polynomial function? f(x)=x^3−x^2−4x+4 select each correct answer. f(x)=0 when x=−1 . (x−1) is a factor of f(x) . f(x) divided by (x−1) has a remainder of 0. f(−1)=0

x = 1 is a root so

f(x)  divided by (x−1)  has a remainder of 0     and

(x−1)  is a factor of  f(x)

x4−4x3−22x2+4x+21    we can write this as

x^4 - 4x^3  - 21x^2  - x^2 + 4x + 21

x^2 ( x^2 - 4x - 21)  -  1 ( x^2 - 4x - 21 )

( x^2 - 1) (x^2 - 4x - 21)

(x + 1) ( x - 1) (x - 7)(x + 3)

The zeroes  are     -1, 1, 7, -3

f(x)  divided by (x−1)  has a remainder of 0.

(x−1)  is a factor of  f(x) .

Step-by-step explanation:

complete test attached

there will be 35 boys in each team. : )

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.
