Answer:
1.38 to the nearest hundredth.
Step-by-step explanation:
Dividing:
 x + 1 ) 3x - 1 ( 3             
           3x + 3
                 -4 
so (3x - 1) / (x + 1) =  3  - 4 / x+ 1
Integral  of (3  - 4 / x+1 )  = 3x - 4 ln(x + 1)
Between  limits of 1 and 2 we have:
(3(2) - 4 ln 3) - (3 - 4 ln2)
=  1.6056 - 0.2274
= 1.3782.
