Which of the following statements must be true about the polynomial function f(x)?
If1+ S13 is a root of f(x), then -1- VT3 is also a root of f(x).
If1 + 131 is a root of f(x), then 1 - 131 is also a root of f(x).
If 13 is a root of f(x), then -13 is also a root of f(x).
If-13 + / is a root of f(x), then 13 + i is also a root of f(x).

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2

96 39 cause 135 -96=39 im smart (i used a calculater)

how to award brainliest:

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.
