Multiply top by top
2 * -3 = -6
Multiply bottom
7 * 8 = 56
The answer is -6/56
Simplify = -3/28
        
             
        
        
        
Answer: (x+1)^2=12(y-2)
Step-by-step explanation: 
 
        
             
        
        
        
 = 1455
 = 1455
generate a few terms of the sequence using  = 3n + 2
 = 3n + 2
 = ( 3 × 1) + 2 = 5
 = ( 3 × 1) + 2 = 5
 = (3 × 2) + 2 = 8
 = (3 × 2) + 2 = 8
 = (3 × 3 ) + 2 = 11
 = (3 × 3 ) + 2 = 11
 = (3 × 4 ) + 2 = 14
 = (3 × 4 ) + 2 = 14
 = ( 3 × 5 ) + 2 = 17
 = ( 3 × 5 ) + 2 = 17
the terms are 5, 8, 11, 14, 17
these are the terms of an arithmetic sequence
sum to n terms is calculated using  =
 =  [ 2a + (n-1)d]
 [ 2a + (n-1)d]
where a is the first term and d the common difference
d = 8 - 5 = 11 - 8 = 14 - 11 = 3 and  = 5
 = 5
 =
 =  [( 2 × 5) + (29 × 3) ]
 [( 2 × 5) + (29 × 3) ]
= 15( 10 + 87) = 15 × 97 = 1455
