the answer is 6 statements
Step-by-step explanation:
 
        
             
        
        
        
The given expression is :
2xx+3-5(x-2)
We know that, 

Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
 
        
             
        
        
        
What you need to do is find a common multiple which is 11, Then you divide 22c and 33d by 11 so you get 2c and 3d Then since there is an addition sign you put 2c and 3d is () 
The Final answer is
11(2c+3d)
        
             
        
        
        
No 5/8 is bigger because half of 8 is 4 and 5 is greater than 4
 
        
             
        
        
        
The length of the first two sides of a triangle must be greater than the length of the last side.  If the longest length were 18, the first two sides would be too short.  36-18=18, 18 is equal not greater than 18 which means the sum of the first two sides are too short.
