(3x-2)(x+1)
3x*x+3x-2x-2
3x^2+3x-2x-2
3x*2+x-2 
I think this is the answer
        
                    
             
        
        
        
Mrs Carson gives the better deal, this is becuase when i set up an inequality 48/6 and 67.50/9, i divided 48 by 2 then added 24 to 48 so i could get them both so i can see what they give, so Mrs Carson gives 72 dollars every 9 hours and thats better than 67.50.
        
             
        
        
        
Answer:
Step-by-step explanation:
3ab + 7a² + 2b² - (7a² - 4ab + 2b²) = 3ab + 7a² + 2b²  - 7a² + 4ab - 2b²
Now combine like term. Like terms have same variable with same power.
 = <u>3ab + 4ab</u>  <u>+ 7a² - 7a²</u>  + <u>2b² - 2b²</u>
= 7ab
 
        
             
        
        
        
Answer:
219.9  feet to the nearest tenth.
Step-by-step explanation:
Use trigonometry:

= 154/x 
x =  154 / tan35
= 219.93
