Answer:
20+24= 2(10+12) = 4(5+6)
Those are two ways to factor 20+24.
 
        
             
        
        
        
Answer:
2/10 or 1/2 = .5 you would divide 2 by 2 and 10 divided by 2 (whatever you multiply or divide by on the top you must do on the bottom)
2/10=.50
3/100=.03 (divide 3 by 10=.0
 
        
                    
             
        
        
        
When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.
u(x) ≥ 0.

9x + 27 ≥ 0 by squaring both sides
9x ≥ -27
x ≥ -3
So the domain of the function is when x ≥ -3 is true.
