Answer:

Step-by-step explanation:

L = 2 + sqrt(2)

W = 4 - 2sqr(2)

Area = L * W

Area = (2 + sqrt(2) )* (4 - 2sqrt(2) )

Use Foil

F: 2*4 = 8
O: 2*(-2sqrt(2) = - 4sqrt(2)
I: 4*sqrt(2)
L: sqrt(2)*(-2sqrt(2) = - 2*2= - 4

Result

Area = 8 - 4 - 4sqrt(2) + 4sqrt(2)

Area = 4

Display the set of data in a histogram.

VARVARA [1.3K]

Answer:

The answer to your question is the third histogram

Step-by-step explanation:

What we must check in a histogram is that the x-axis is represented the intervals and in the y-axis is represented the frequency.

The first histogram is incorrect just by observing the first bar, we notice that the correct frequency from 0 to 4 is 3, not 14. This histogram is incorrect.

Also, the second histogram is incorrect, the frequency of the first category is 3, not 12. This histogram is wrong.

The third histogram is correct because all the bars are in agreement with their frequencies.

The last histogram is incorrect, for example, the last frequency is 12, not 3.

Wewaii [24]

the length of the fish tank is $length=13cm$ . Correct option is A)

<u>Step-by-step explanation:</u>

Here we have , Peter has just purchased a small rectangular fish tank that holds 910 milliliters of water. The tank has a width of 7 cm and a height of 10 cm. We need to find What is the length of the fish tank . Let's find out:

The fish tank is in the shape of cuboid , and we know that volume of cuboid :

⇒ $Volume = length(width)(height)$

Now , according to question we have following parameters :

$V=910ml=910cm^3\\w=7cm\\h=10cm$

Therefore , Putting theses values in above equation we get :

⇒ $Volume = length(width)(height)$

⇒ $910 = length(7)(10)$

⇒ $910 = length(70)$

⇒ $length=13cm$

Therefore , the length of the fish tank is $length=13cm$ . Correct option is A)

The answer is 46, The solution is listed below:

$\sqrt{2x+8}-6=4 \\ \\ 
 \sqrt{2x+8}=10 \\ \\ 
2x+8=(10)^{2} \\ \\ 
2x+8=100 \\ \\ 
2x=92 \\ \\ 
x= 46$
