X2y4(x2 - 16) - 9y4(x4 - 16) how do i simply this?
e-lub [12.9K]

Answer:

The simplified expression is given as

8x^2y^4(17x^2-2)

Step-by-step explanation:

step one:

Given the expression

x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)

step two:

First, let us open the bracket we have

x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)\\\\x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\

step three:

collect like terms we have

x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\x^4y^4-9x^4y^4+144x^4y^4-16x^2y^4\\\\-8x^4y^4+144x^4y^4-16x^2y^4\\\\136x^4y^4-16x^2y^4\\\\\\

step four:

we can now factor out 8x^2y^4we have

8x^2y^4(17x^2-2)

Allison bought a 36 piece box of chocolates. 1/3 were creams 1/4 were nuts
ki77a [65]
A.
1/3 were creams
1/3 of 36 means 1/3 times 36 or 1/3 times 36/1=36/3=12 (by long division or times tables)

B.
1/4 of all or 36, so 1/4 of 36 is 36/4=9 (by long divison or times tables)

C. so we do total-creams-nuts=rest
36-12-9=15 other






A. 12
B. 9
C. 15

if 2000 Qr is equal to 157960 NC and 1 HKD is equal to 13.62 NC then how many QR is equal to HKD 315920​
Airida [17]

Using proportions, it is found that 5449.62 QR is equal to HKD 315920​.

<h3>Proportions</h3>
  • This question is solved by <em>proportions</em>, using a rule of three.

<h3>Conversion of KR to HKD:</h3>
  • 2000 Qr are equal to 157960 NC. 1 HKD is equal to 13.62 NC, hence, how many QR are worth 13.62 NC?

Hence, the <em>rule of three</em> is:

2000 QR - 157960 NC

x QR - 13.62 NC

Applying cross multiplication:

157960x = 200(13.62)

x = \frac{200(13.62)}{157960}

x = 0.01725

Then:

  • We have that 1 HKD is equals to 0.01725 QR. How many QR are equal to HKD 315920​?

Then, the second <em>rule of three</em> is:

1 HKD - 0.01725 QR

315920 HKD - x QR

Applying <em>cross multiplication:</em>

x = 0.01725(315920) = 5449.62

5449.62 QR is equal to HKD 315920​.

How many ways can eight girls sit together in a row?
defon

In 10080 ways

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

We first treat the two people how have to sit together as 1 item taking up 2 seats so they have 7 possibilities of seats i.e. 12 23 34 45 56 67 78 and the two of them can sit in 2 possible ways, AB or BA

Now, the other 6 people will have 6 seats to choose from. So the total number of ways they can sit is 6 for the first person 5 for the second and so on so its 6!

Thus, the total number is 7 \times 2 \times 6 ! = 10 080
