5. The distance that a car crosses is given by the equation:

distance = speed * time

The distance that the car car covers is given by the
polynomial: 2x^2 + 19x + 30

What is one possible expression for the values of speed and time?

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

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
