Answer:

81(x + 2y)(x - 2y)

Step-by-step explanation:

81 {x}^{2}  - 324 {y}^{2}  \\  \\  =  {(9x)}^{2}  -  {(18y)}^{2}  \\  \\  = (9x + 18y)(9x - 18y) \\  \\  = 9(x + 2y) \times 9(x - 2y) \\  \\  = 81(x + 2y)(x - 2y)

I HAVE 1 MORE DAY TO TURN THIS IN SO HURRY
SCORPION-xisa [38]

Hello there! I am EnjoyingLife, and I hope you find my answer helpful.

First of all, since all books cost less than $5, the most expensive a book could be is $4.99 (remember, less than, not less than or equal to)

Now, let's write an inequality to represent the cost of books.

We know that all books cost less than $5.

We have a sign for "less than". It's "<"

Thus,

p<5

Hope it helps!

Have an awesome day!

Good luck!

3x+12-6x&lt;-9<br><img src="https://tex.z-dn.net/?f=3x%20%2B%2012%20-%206x%20%20%5Cleqslant%20%20-%209" id="TexFormula1" title="

First simplify 3x + 12 - 6x to -3x - 12
Next subtract 12 from both sides
Next subtract -9 - 12 and that would be -21
Next divide both sides by -3
Next lets simplify the fraction -21/-3 into 21/3 since those two negatives make a positive.
Lastly simplify the fraction 21/3 to get the answer.

Allison, Brianna, and Celeste went on a hike. Allison brought 9 homemade
poizon [28]

Answer:

Allison = $0.27

Brianna = $1.89

Step-by-step explanation:

The total cookies that the three girls have are:

Allison's cookies + Brianna's Cookies

= 9+15

=24

There is a total of 24 cookies which has to be divided between the 3.

So

Each girl gets 24/3 = 8 cookies.

Since Celeste had no cookies she will have to pay for the 8 cookies.

Allison had 9, she will give one to Celeste

Brianna had 15 out of which she will use 8 for her self and 7 will be given to Celeste.

Celeste is paying 2.16 for 8 cookies.

Price of one cookie = 2.16/8

=$0.27

So, amount that will be given to Allison = 0.27 * 1 = $0.27

Amount that will be given to Brianna = 0.27 * 7 = $1.89

There is a bag filled with 5 blue and 4 red marbles.
Delvig [45]

Answer:

8/18=4/9

Step-by-step explanation:

since it there is 1/6 for red marbles and 5/18 for blue marbles it works because it is 8*9=72 for the denominator and 4*3=12 so it is 12/72=1/6 and for blue it is 5/18 because it is 5*4=20 and 20/72=10/36=5/18 so it is 1/6+5/18=8/18=4/9
