Answer:
2.85 in²
Step-by-step explanation:
Area of triangle = 1/2 x base x height
1/2 x 1.9 x 3 = 2.85 in²
 
        
             
        
        
        
Answer:
neither arithmetic nor geometric
Step-by-step explanation:
16, 12, 32, 92, ... 
For arithmetic , there should be a common difference
16, 12, 32, 92, ... 
Lets find the difference of two consecutive terms
12-16 = -4
32 - 12 = 20
92 - 32 = 60
Common difference is not same so it is not arithmetic
For Geometric , there should be a common ratio
16, 12, 32, 92, ... 
Lets find the ratio of two consecutive terms



Common ratio is not same , so it is not Geometric
So answer is neither arithmetic nor geometric
 
        
             
        
        
        
Answer:
6x + 1
Step-by-step explanation:
Distribute
3 + 2 ( x- 1 ) + 4x
3 + 2x - 2 + 4x
Subtract 
3 + 2x - 2 + 4x
1 + 2x + 4x
Like terms
1 + 2x + 4x
1 + 6x
Rearrange
6x + 1
