Which of the following is a polynomial with roots 5, 4i, and −4i?

, for any real a.

Step-by-step explanation:

The three roots of a polynomial is given

Hence the polynomial would be cubic having factors as

x-5, x+4i and x-4i

Multiplying we get

This would be the possible least degree polynomial with the given roots.

Even if we multiply this by any real number, roots would remain the same

Hence cubic polynomial is

for some real a.

probably .5

i can on others if necessary.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
