  • <em>Answer:</em>

<em>x³ + x²y - xy² - y³</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there !</em>

<em>(x − y)(x² + 2xy + y²) =</em>

<em>= x(x² + 2xy + y²) - y(x² + 2xy + y²)</em>

<em>= x³ + 2x²y + xy² - x²y - 2xy² - y³</em>

<em>= x³ + x²y - xy² - y³</em>

<em>Good luck !</em>

An online retailer is offering a 30% savings on your total order. You decide to purchase a pair of pants for $82, two shirts for
Natali [406]

Answer:

$233.39

Step-by-step explanation:

Pants = $82, 2 Shirts = $53 * 2, Shoes = $120

Add all these values up to find the total cost of your order excluding tax.

82 + 53(2) + 120 = 308

Next find the price w/ tax. Multiply 308 by 8.25%, or 0.0825.

308 * 0.0825 = 25.41

Now you add the tax to the total value.

308 + 25.41 = 333.41

The total value including tax is $333.41. The online retailer is offering a 30% savings (discount), so multiply the total price including tax by 30% (0.30).

333.41 * 0.30 = 100.023

Now you subtract the discount from the total price.

333.41 - 100.023 = 233.38700

The question say the answer rounded to the nearest cent or hundredths, so your final answer is 233.39.

The final price of the clothing including all discounts and taxes is $233.39.

With compound interest, what happens when you start compounding more and more frequently?
VLD [36.1K]
Your money grows faster because the interest is added back into the principle and then the next time it compounds you get interest on the new principle amount.  So for example, you deposit $100 in an account that gets 5% interest compounded semiannually. The first time it compounds you get $5 added to your account so your new balance is $105.  The next time it compounds you get 5% on $105 so you get $5.25 added and so on.  If this is only happening semi-annually that would be all you get for the year.  But if it happens quarterly you would get would get deposits of $5.51 and $5.79 as well.  If it compounds monthly or even daily your money would grow more and more.  Hope this helps.

Solve this system of equations by using the elimination method -2x-2y=-6, 3x+4y=8
adoni [48]

Step-by-step explanation:

- 2x-2y=-6

3x+4y=8

multiply equation (1) by 3 and equation (2) by 2

- 6x-6y=18

6x+8y=16

Add

2y=34

y= 34÷2

y=17

substitute 17 for y in equation (2)

3x+4y=8

3x+4(17)=8

3x+68=8

3x=8-68

3x=-60

x=-60÷3

x=-20

x=-20,y=17

Find the centroid for an area defined by the equations y = x² + 3 and y = - (x – 2)² + 7
sergeinik [125]
First we need to find where the 2 graphs intercept.

x^2 + 3 = - (x^2 - 4x + 4) + 7
x^2 + 3 = -x^2 + 4x + 3
2x^2 - 4x = 0 
2x(x - 2)

x = 0 , 2. are x coordinates  of the 2 intercepts.
