Answer:

x + 4√(x + 2) + 6

Step-by-step explanation:

All we need to do is expand by using FOIL (First, Outside, Inside, Last):

x + 2 + 2√(x + 2) + 2√(x + 2) + 4

Then we combine like terms to get our final answer:

x + 2 + 4√(x + 2) + 4

x + 4√(x + 2) + 6

The length of the rectangle is 3 times its width.
Blizzard [7]

Answer:

Since length is three times, hence it is 6 inches.

let the width be x.

then, length= 3x

perimeter= 16 inches.

perimeter of a rectangle = 2( L+B)

2(3x+x)=16.

3x+x= 16÷2

4x= 8

x= 2

since length=3x

hence, 3×2= 6 inches

The answer at the bottom is (1,3) please help
Novosadov [1.4K]

Answer:

(3,1)

Step-by-step explanation:

Since both equations are equal to y, we can set them equal to each other

y = 3x-8

y = 4-x

3x-8 = 4-x

Add x to each side

3x+x-8 = 4-x+x

4x-8 = 4

Add 8 to each side

4x-8+8 = 4+8

4x = 12

Divide each side by 4

4x/4 =12/4

x=3

Now we can find y

y = 4-x

y = 4-3 =1

A statistical test is performed for assessing if men have a longer mean nose length than women. The p-value is 0.225. Which of t
BlackZzzverrR [31]

Answer:

The most appropriate way to state the conclusion is:

d. There is not enough evidence to say that men have a longer mean nose length than women.

Step-by-step explanation:

We have the result of a hypothesis test.

The claim was that men have a longer mean nose length than women.

That means that the alternative hypothesis states that men's mean nose length is higher than the women's mean nose length.

H_0: \mu_1-\mu_2=0\\\\H_a:\mu_1-\mu_2> 0

The P-value of the test is 0.225, which for any usual significance level is large enough to fail to reject the null hypothesis. Then, there is no enough evidence to support the claim that men have a longer mean nose length than women.

a. Men have a longer mean nose length than women.

FALSE. There is no enough evidence to support the claim.

b. The probability is 0.225 that men and women have the same mean nose length.

FALSE. That is not the meaning of the P-value.

c. The mean nose lengths of the populations of men and women are identical.

FALSE. We can not claim that the null hypothesis is true, even when we havo no enough evidence to reject it.

d. There is not enough evidence to say that men have a longer mean nose length than women.

TRUE. This is the the most appropriate way to state the conclusion.
