Let n be the larger integer and n-2 be the smaller integer.

n² - (n - 2)²

= n² - (n - 2)(n - 2)

= n² - (n² - 4n - 4)

= n² - n² + 4n + 4

= 4n + 4

= 4(n + 1)

No matter what value n is, it will always be a multiple of 4.

<h3>What are fractions?</h3>

The fraction is defined as the division of the whole part into an equal number of parts. here we have the following information Vassil rounded to the nearest half to estimate the product of Five-eighths and StartFraction 8 over 9 EndFraction.

E =  \dfrac{5}{8}\times \dfrac{8}{9} = 0.55

Thus the product of the fraction estimated in the nearest half is,

0.5×1= 0.50

Therefore the correct answer is option B which is the actual product is about StartFraction 1 over 18 EndFraction less than the estimate.

Brooke saved the same amount of money each week for four weeks. She made this table to show how much money she saved.
Musya8 [376]

Answer:

In 10 weeks of time, Brooke would  earn $ 20.

Step-by-step explanation:

Here, according to the table:

The money saved in week 1   =  $ 2   =   $(1  x 2)

The money saved in week 2  =  $ 4   =  $ ( 2 x 2)

The money saved in week 3   =  $ 6  =  $ ( 3 x 2)

The money saved in week 4   =  $ 8 =   $ ( 4 x 2)

So, by the graph relation, we can see that:

The amount saved in n weeks = ( n x 2) dollars

So, the amount saved by Brooke in 10 weeks is:

Put n =  10, we get:

The money saved  = 2 n = 2 x 10 = $ 20

Hence, in 10 weeks of time, Brooke would  earn $ 20.
