Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. n^2-4n/3

ololo11 [35]

Answer:

(n- 2/3)²

Step-by-step explanation:

<em>Perfect square trinomial is: </em><em>a²+2ab+b²= (a+b)²</em>

We have:

n² - 4n/3

It can be put as:

n² -2×n×2/3

Here we consider n = a and -2/3 = b, then

b²= (-2/3)²= 4/9

Now we add 4/9 to a given binomial to make it perfect square:

n² - 2×n×3/2 + 4/9= (n- 2/3)²

So, added 4/9 and got a perfect square (n- 2/3)²

Preston's salary before taxes are taken out is p dollars. After taxes taken out, Preston's take home salary is t dollars. If p =

Karolina [17]

Answer:

$After\ Tax = \frac{p}{1.25}$

Step-by-step explanation:

Given:

$Before\ Tax =\$ p$

$After\ Tax =\$ t$

$p = 1.25t$

Required

Determine his after tax salary in terms of p

To do this, we simply make t the subject in $p = 1.25t$

Divide both sides by 1.25

$\frac{p}{1.25} = \frac{1.25t}{1.25}$

$\frac{p}{1.25} = t$

$t = \frac{p}{1.25}$

Substitute p/1.25 for t in $After\ Tax =\$ t$

$After\ Tax = \frac{p}{1.25}$
