22. Use the information from Question 21. Show how the Distributive Property can be used to find the area of Marlene's living room. 23 Use the algebraic expression for length and width of Marlene's living room found in the diagram and the value of x found in Question 21C

A. find the actual length and width of her living room.

B. Find the actual area of Marlene's living room use actual dimensions.

420 feet

Step-by-step explanation:

x=14, so you plug in 14 for x*(x+2)

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
