Answer:

$n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}$ -- Perfect square trinomial

$(n + \frac{1}{3})^2 = \frac{1}{9}$ ---Binomial squared

Step-by-step explanation:

Given

$n^2 + \frac{2n}{3}$

Solving (a): Perfect square trinomial

We have:

$n^2 + \frac{2n}{3}$

Express as an equation

$n^2 + \frac{2n}{3} =$

Start----------------------------

Take coefficient of n i.e. (2/3)

Half it: i.e. (1/3)

Square it: (1/63^2

Add to both sides of the equation

---------------------------End

So, we have:

$n^2 + \frac{2n}{3} + (\frac{1}{3})^2 = (\frac{1}{3})^2$

Remove brackets

$n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}$

Solving (b): Binomial Squared

$n^2 + \frac{2n}{3} + \frac{1}{9} = \frac{1}{9}$

Expand

$n^2 + \frac{n}{3}+ \frac{n}{3} + \frac{1}{9} = \frac{1}{9}$

Factorize:

$n(n + \frac{1}{3})+ \frac{1}{3}(n + \frac{1}{3}) = \frac{1}{9}$

Factor out n + 1/3

$(n + \frac{1}{3})(n + \frac{1}{3}) = \frac{1}{9}$

Express as square

$(n + \frac{1}{3})^2 = \frac{1}{9}$

Answer:

Step-by-step explanation:

convert 42% to 0.42 them multiple 200 X 0.42 = 84

84 = cards in mint condition

200 - 84 = 116

116 = cards not in mint condition
