What is the additive inverse of the polynomial –9xy2 + 6x2y – 5x3? –9xy2 – 6x2y + 5x3 –9xy2 – 6x2y – 5x3 9xy2 + 6x2y + 5x3 9xy2 – 6x2y + 5x3

4th Option is correct.

Step-by-step explanation:

Given Polynomial is

We need to find additive inverse of the given polynomial.

We know that Additive inverse of a is given by -a.

So, Additive inverse of polynomial p(x) is given -p(x)

let,

So, Additive incverse of p(x) =

Therefore, 4th Option is correct.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
