Answer:
3(a +3)
Step-by-step explanation:
(a+3)^2 -a(a+3)
FOIL
a^2 +3a+3a+9 -a(a+3)
Distribute
a^2 +3a +3a +9 -a^2 -3a
Combine like terms
3a +9
FACTOR out a+3
(a+3)( a+3 -a)
(a+3) (3)
3(a+3)
 
        
                    
             
        
        
        
Answer:
y=8x
Step-by-step explanation:
an equation follows the structure of y=mx+b where m is the slope and b is the y-intercept for this line the y intercept is 0 so you dont have to include it in your equation and the slope = rise over run so 8/1=the slope if you put it into an equation the answer is y=8x
 
        
                    
             
        
        
        
Let us consider 48 as 100%
so,
48------------->100
x -------------->75
therefore,
100*x=48*75
x=(48*75)/100
x=36
        
             
        
        
        
The answer is:  [B]:  " 45.5 degrees " .

<span>The answer is that x = 21/9. 
Start with the original:                  4(2x - 1) - 7 = 4 - x + 6
Now distribute the 4:</span>                   <span> 8x - 4 - 7 = 4 - x + 6. 
Now combine the like terms.       8x - 11 = -x + 10. 
Now add x to both sides.             9x - 11 = 10. 
Now add 11 to both sides.            9x = 21. 
And divide by 9 on both side.      x = 21/9. </span>
