Answer:
1) yes  2) no  3) yes
Step-by-step explanation:
The lengths of the two shorter sides must be greater than the length of the longest side.
1) 8 + 9 > 10    yes
2) 1 + 1 = 2      no
3)  6 + 8 > 9    yes
 
        
             
        
        
        
Answer:
129.99
Step-by-step explanation:
129.99 rounds to 130 because the 9 in the hundredths place causes the 9 in the tenths place to round up, making the number 130.0.
 
        
                    
             
        
        
        
Elena's total cost (C) is 5(9.98 + 24.99 + x)
Since each dog leashes cost $9.98, each bag of dog food cost $24.99 and each crate of egg cost $x, hence:
Total cost (C) = 5 * $9.98 + (5 * 24.99) + (5 * x)
C = 5(9.98 + 24.99 + x)
Therefore Elena's total cost (C) is 5(9.98 + 24.99 + x)

The answer is d.
Finding area of ABCD :
- Find side length
     2. Apply formula to find area
Finding area of GHIA :
Finding area of DEFG :
Now, let's see whether is true.
- Area (ABCD) - Area (GHIA) = Area (DEFG)
- 25 - 16 = 9
- 9 = 9
∴ Hence, it is proved √
