Answer:
7r³ - 3r² + 20r
Step-by-step explanation:
(9r³ + 5r² + 11r) + (-2r³ + 9r - 8r²)
You can get rid of the parentheses since there is nothing to distribute.
9r³ + 5r² + 11r - 2r³ + 9r - 8r²
Combine like factors.
7r³ - 3r² + 20r

</em>
<u><em>PLEASE</em><em> </em><em>MAKR</em><em> </em><em>ME</em><em> </em><em>BRAINLIEST</em><em> </em><em>IF</em><em> </em><em>YOU</em><em> </em><em>ARE</em><em> </em><em>HAPPY</em><em> </em><em>WITH</em><em> </em><em>THE</em><em> </em><em>ANSWER</em></u>
First put it in decreasing power according to x.
x^4-5x+8+x^2
=x^4+x^2-5x+8
Now this question is asking what is the highest degree of x you see in this function.
4 of course.
Therefore the answer to his question is degree of 4.
Done!
