Polynomials perimeter and area photo above

Perimeter  or   units

Area  or square units

Step-by-step explanation:

A. Perimeter is Twice the length plus twice the length. P =2(l + w)

or P = 2L + 2W . Substitute the values given into the formula and Calculate.

P = 2[(2x + 5)(x-1) + 2(2-3x)] . becomes ,

then   add like terms and simplify

B. Area is Length times Width. Substitute the given values and calculate.

(2x + 5)(x-1)×(2-3x)  (2x + 5)(x-1)(-3x+2)

It is difficult to imagine an actual rectangle with such dimensions. It's math theory.

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
