Hey there!

Answer = x^{2}+2x

Explanation:

Let's simplify step-by-step.

x(x + 3) -x

Distribute:

= (x)(x) + (x)(3) + -x

= x^{2}+3x+-x

Combine Like Terms:

= x^{2}+3x+-x

= (x^{2})+(3x+-x)

= x^{2}+2x

So therefore, that is how you found your answer: x^{2}+2x

A student studying his classmates' cars' ages reports the 5-number summary as {1, 3, 4, 8, 20}. what is the iqr for his data?
timurjin [86]

IQR for the data {1, 3, 4, 8, 20} is 5.

Interquartile Range(IQR) for a data is defined as the difference between third quartile and first quartile.

denoted by  IQR=Q₃-Q₁              (Q₃ is third quartile and Q₁ is first quartile)

The five number summary of a data set is represented as

{minimum, first quartile , second quartile , third quartile , maximum}..…(1)

According to the question

{1, 3, 4, 8, 20}

On comparing it with equation   …(1)

minimum=1

Q₁ =3    , Q₂=4 , Q₃=8 , maximum =20

IQR=Q₃-Q₁

Substituting the values we get

IQR=8-3=5.

Therefore , Interquartile Range for the data {1, 3, 4, 8, 20} is 5.

1.64 as a fraction in simplest form
mrs_skeptik [129]
<span>The correct answer is 1 16/25.

Explanation<span>:
This is read as "one and sixty-four one-hundredths." This means the fraction would be 1 64/100.

Both numerator and denominator are even, so we will divide both by 2 and get 1 32/50.

Again, both are even, so we divide by 2 again and get 1 16/25.</span></span>

Simple interest $1600.00 at 6% for 180 days
ikadub [295]

Answer:

Interest = $47.34

Step-by-step explanation:

Formula:-

Simple interest I = PNR/100

P - Principle amount  

N - number of years

R - Rate of interest

It is given that

P = $ 1600

R = 6%

Number of days = 180 days

<u>To find the simple interest for 1 year(365 days) </u>

I = PNR/100

= (1600 * 1 * 6)/100 = $96

<u>To find the interest for 180 days </u>

For 365 day I = $96

For 180 days I = (180/365) * 96

I  = $47.34
