Answer:

$\boxed{x^3 + xy^2 + yx^2 + y^3}$

Step-by-step explanation:

$\frac{x^4 - y^4}{x - y}$

$= \frac{(x^2)^2 - (y^2)^2}{x - y}$

$= \frac{(x^2 - y^2)(x^2 + y^2)}{x - y}$

$= \frac{(x - y)(x + y)(x^2+y^2)}{x - y}$

$= (x + y)(x^2 + y^2)$

$= x^3 + xy^2 + yx^2 + y^3$

Hello!

First you have to add the number of fish

52 + 61 + 87 = 200

Then you find the percentage of grass carps

61/200 = 0.305

Then you multiply what you just got with the estimated sample

800 * 0.305 = 244

The answer is 244

Hope this helps!

If a TV cost $3960.00 and toes on sale during the following week with a 25% discount, what will be the total cost of the TV? but

Free_Kalibri [48]

we have the price of TV is $3960.if we round off to the nearest tens we get same 3960 because we have 0 at the end which means lesser than 5 so 60 will be the nearest ten.

discount = $\frac{25}{100} *3960=990$

so $990 will be the discount.

and the cost of TV after discount is $3960-990=$2970$

Ashley deposits $1000 into an account that earns 4% interest compounded 2 times per year. how much money will Ashley have in her

loris [4]

The equation for compound interest is $A=P(1+\frac{r}{n})^{nt}$ , where:
P is the original deposit (or "principal")
r is the rate of the interest (in decimal form)
n is the number of times per year that the interest is compounded
t is the time passed in years

Plugging in your values, we see that the equation becomes $A=1000(1+\frac{.04}{2})^{(2)(5)}=1000(1.02)^{10}$

which equals, to the nearest cent, $1218.99, which is answer C.

Question 5(Multiple Choice Worth 1 points)

Anit [1.1K]

Answer:

x+3x+5=101 (Option C).

Step-by-step explanation:

This question requires to be solved using the supposition method.

Let Aylen's savings be $x. Therefore, Rich's savings would be $(3x+5). This is because it is mentioned that Rich has $5 more than 3 times the amount of money Aylen has. The sum of the savings is $101. Therefore the sum of the savings of Aylen and Rich is given by:

x + 3x + 5 = 101. Thus, Option C is the correct answer.

Solve the equation for x gives x = $24. This is Aylen's share. To calculate Rich's share, simply put x=24 in 3x+5. Thus, Rich's share will be $77.

In short, Rich's share = $77, Alan's share = $24, and this has been calculated using the equation x+3x+5=101 (Option C)!!!
