Answer:
What is the simplified form of this expression?
7a2 + 10a − 3a − 2a2
Step-by-step explanation:
7a2 + 10a − 3a − 2a2
Combine like terms
742 + 10a - 3a - 2a2
742 + 7a - 2a2
solution=
5a2 + 7a
 
        
                    
             
        
        
        
Answer:
15 yards
Step-by-step explanation:
proportion:
2/5:6/X
2x=30
x=15
 
        
             
        
        
        
1/4 hour because since it took him 3/4 hr to milk 3 groups, it is reasonable to divide 3/4 by 3. So in 1/4 hour.
        
             
        
        
        
This is a pythagorean triple --> 3-4-5
Although you notice it is doubled but with the same pattern --> 6-8-10
Thus, the hypotenuse is 10. 
        
                    
             
        
        
        
Okay so for 2x-y > 3
Subtract -2 from each side 
-y>-2x+3
Divide by -1 
And when you divid you gotta switch signs 
So it’s y<2x-3
3x-5y less than and equal to 25
Subtract 3 
-5y is less than and equal to -3x+25
Then divide by -5
Flip since we divide 
Y more than and equal to 3/5x-5
We always flip signs when we divid or multiple 
I hope this help 
Sorry if I’m wrong
