Answer:
If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents and a repeat of step 3. Step 6: Raise each coefficient (or number) to the appropriate power and then simplify or reduce any remaining fractions. Step 1: Apply the Zero-Exponent Rule.
 
        
                    
             
        
        
        
Answer:
11
Step-by-step explanation:
2(l+w)
40= 2(9+x)
40= 18+2x
Subtract 18 from 40
22=2x
Divide 2x by itself and 22
11=x or x=11
 
        
                    
             
        
        
        
B. To be careful, use brackets: 10(1*2) + 4x which will be 20 + 40x or as you have it, 10*2 + 40x.
