Answer:

\frac{x^2+5x+6}{x+2}

⇒ x+3

Step-by-step explanation:

To simplify:

\frac{x^2+5x+6}{x+2}

To simplify the given expression we need to factor the numerator.

We have

x^2+5x+6

Using split the middle term method by splitting 5x into two terms ax and bx such that ax+bx=5x and ax(bx)=6x^2

We see that [ax=2x and bx=3x]

Thus we can write

⇒ x^2+2x+3x+6

Factoring in pairs by taking the GCF of terms in pairs.

⇒ x(x+2)+3(x+2)

Factoring the whole expression as (x+2)is a common factor.

⇒ (x+2)(x+3)

Now, the expression can be rewritten as:

\frac{(x+2)(x+3)}{x+2}  

Canceling out the common expressions, we have.

⇒ x+3

Brittany opened a savings account with an annual interest rate of 10% and an initial deposit of $7000. If her interest is compou
GenaCL600 [577]

Initial Deposit = $7000

It means P= $7000

rate of interest = 10%

So , r = 0.10

compounded quarterly , so  n = 4

and we have to find the amount after 5 years , So t = 5


Now the formula we use here is

A= P(1+\frac{r}{n} )^{nt}

A= 7000(1+\frac{0.10}{4} )^{(4)(5)}

A= 7000(1.025 )^{(20)}

A= 7000(1.63861644029)

A= 11470.315


So amount after 5 years = $11470.315

Melissa walked at a rate of 88 feet per minute. What was her approximate speed to the nearest tenth of a mile per hour?
GREYUIT [131]

Answer:

1.0 mph

Step-by-step explanation:

so there are 60 minutes in an hour

you need to find what her speed is per hour

right now it is per minute

so multiply her current speed by 60

88*60=5280

there are 5280 feet in a mile.

Her current speed is 1 mile per minute

rounded to the nearest tenth of a mile is

1.0 mph

In August 2003, 56% of employed adults in the United States reported that basic mathematical skills were critical or very import
Serga [27]

Answer:

Yes

Step-by-step explanation:

First, suppose that nothing has changed, and possibility p is still 0.56. It's our null hypothesis. Now, we've got Bernoulli distribution, but 30 is big enough to consider Gaussian distribution instead.

It has mean μ= np =  30×0.56=16.8

standard deviation s = √npq

sqrt(30×0.56×(1-0.56)) = 2.71

So 21 is (21-16.8)/2.71 = 1.5494 standard deviations above the mean. So the level increased with a ˜ 0.005 level of significance, and there is sufficient evidence.
