Answer: 
x^3-4x^2-5x+3 
explanation:
multiply each term in the parentheses by X squared
x(x^2)-4x^2-5x+3
        
             
        
        
        
Answer:

The data in order looks like so:
98.6, 99.7, 100.2, 101.8, 102.9, 103.6 
Take the greatest value and subtract it from the least value to get the range of the data:
103.6-98.6=5
5 is your answer
Hope this helps!

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
