Hi there!

I believe your answer is:

$n = 13$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Solving for 'n'...}}\\\\9 = n - 4\\-------------\\\rightarrow n - 4 = 9\\\\\rightarrow n - 4 + 4 = 9 + 4\\\\\rightarrow \boxed{n=13}\\$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Answer:

-2

Step-by-step explanation:

To find the slope of a line, you need to find the $\frac{rise}{run}$ between two points. I will be using the points (-3, 2) and (-1, -2).

$\frac{rise}{run}$ = $\frac{-2-2}{-1-(-3)}$

= $\frac{-2-2}{-1+3}$

= $\frac{-4}{2}$

= -2

The sum of two numbers is twenty-four. The difference of the two numbers is four.

RSB [31]

Answer:

$x + y = 24$

$x - y = 4$

Now, add these two equations.

You get,

$2x = 28$

$x = \frac{28}{2}$

$x = 14$

Given,

$x + y = 24$

$14 + y = 24$

$y = 24 - 14$

$y = 10$

You can test this to the other equation as well.

$x - y = 4$

$14 - 10 = 4$

Hence, the two numbers are 14 and 10.

(a + b)(a ² - ab + b ²)

erastova [34]

Hi there!

You can use distributive property to solve this equation.

These are the list of terms you have to multiply :
a × a² = a³
a × -ab = -a²b
a × b² = ab²
b × a² = a²b
b × -ab = -ab²
b × b² = b³

add all of those terms...
a³ - a²b + ab² +a²b -ab² + b³
simplify by adding like terms... (- a²b + a²b , ab² - ab²)

a³ + b³

Hope this helped!! :)
