What is the product?
(7x2)(2x + 5) (*-4x-9)
14x5 – x4 - 46x3 - 58x2 - 20x-45
14x6 – 56x5 – 91x4 – 140x3 - 315x2
14x? - 56x6 – 126x5 + 35x4 - 140x3 - 315x2
0 14x12 - 182x + 35x4 - 455x2

72 is the answer to this problem

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
