What are the non permissible values of (2n-5)/(3n+1)

n= -1/3

Step-by-step explanation:

To find non permissible values (npv), focus on the denominator of an expression

In this case, the denominator is:  (3n+1)

The npv is basically the value that would make the expression equal to 0

So, make the expression in the denominator equal 0

     3n+1 = 0

Solve for n

    3n= -1

    n = (-1/3)

Thus, the npv for this equation is n= -1/3

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
