Factorise
2x2 + 7x + 5

7x + 9

Explanation:

To factorize the given expression, we must start by simplifying. In other words, multiply two by two.

2 × 2 + 7x + 5

4 + 7x + 5

Next, we will further simplify the expression by combining like terms. In other words, add four and five together.

4 + 7x + 5

7x + 4 + 5

7x + 9

The expression has now been factorized to its simplest form.

Therefore, the factorized expression of 2 × 2 + 7x + 5 is 7x + 9.

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
