If you would like to solve (x^3 + 8) / (x + 2), you can do this using the following steps:

x^3 + 8 = (x + 2) * (x^2 - 2x + 4)

(x^3 + 8) / (x + 2) = (x + 2) * (x^2 - 2x + 4) / (x + 2) = <span>x^2 - 2x + 4
</span>
The correct result would be <span>x^2 - 2x + 4.</span>

As the Question is not clear

But there are two possibilities

1. \frac{x^3+8}{x+2}=\frac{(x+2)(x^2-2 x+4)}{x+2}=x^2-2 x+4→→Cancelling x+2 from numerator and denominator

→→ Using the formula (a³ + b³) =(a+b)(a² - ab + b²)

Or if

\frac{x^3-8}{x-2}=\frac{(x-2)(x^2+2x+4)}{x-2}=x^2+ 2 x +4→→Cancelling x-2 from numerator and denominator

Using the formula (a³ - b³) =(a-b)(a² + ab + b²)

Statement (1) appears true.

So, correct option is  x²- 2 x + 4 or x² + 2 x + 4

How are the two functions f(x) = 0.7(6)x and g(x) = 0.7(6)–x related to each other?
Harlamova29_29 [7]
The answer
f(x) = 0.7(6)x = <span>f(x) = 0.7(6)^x, and  </span><span>g(x) = 0.7(6)–x= </span>g(x) = 0.7(6)^-x=1/<span>0.7(6)^x
so </span>
g(x) =1/<span>0.7(6)^x=1 /</span><span><span>f(x)

</span> the relationship between f and g are </span>g(x) =1 /<span>f(x) or </span><span>g(x) . <span>f(x) = 1</span> </span>

One number is 5 more than another. the difference between their squares is 155. what are the numbers
kirza4 [7]

the smaller number is 13 and the larger one is 18.

Let's say that the smaller number is x and the larger one is y.

Giving the equation x + 5 = y

This would also make the equation y^2-x^2= 155

to solve let's simplify to find what y^2 is in x terms.

y^2 = (x+5) (x+5) = x^2 +10x + 25.

therefore x^2 + 10x + 25 -x^2= 155

10x + 25 = 155

10x = 130

x = 13

y = 18

Find the solution of this system of equations -2x + 8y = 14 -2x – 2y = -26
Elodia [21]
X cancels out, 8y + 2y is equal to 10y, and 26 + 14 is 40, so y=4
