Using PEMDAS
P = 1x1+9x(0.01)+1x(0.001)
E = no change
M = 1+0.09+0.001
D = no change
A = 1.091
S = no change
final answer is 1.091

Answer:
(3x+1)^2
Step-by-step explanation:
 
        
                    
             
        
        
        
Well, you can only combine the numbers with the variable (the x) in front of them, since there’s no other number on the left side of the equation to combine that lone number with
(example: 3x+2+5x; you can only add 3x and 5x together since 2 has no x). 
So 3x and -2/9x would be your answer.
