Multiply (x + - 1)3 (x + 1)3 = (x + 1)(x + 1)2
= (x + 1)(x2 + 2x + 1)
= x + 1x2 +
x +

(x +-1)3 (x + 1)3 = (x + 1)(x + 1)2

= (x + 1)(x2 + 2x + 1)

= x3 + 3 x2 + 3x + 1

Step-by-step explanation:

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
