Which of the following expressions is this one equivalent to?

schepotkina [342]

Answer: C. x-2

Step-by-step explanation:

We have the following expression:

$\frac{x^{4} -2x^{3} +x-2}{x^{3}+1}$

Factoring in the numerator:

$\frac{x(x^{3}+1)-2(x^{3}+1)}{x^{3}+1}$

Factoring again in the numerator with common factor $x^{3}+1$ :

$\frac{(x^{3}+1)(x-2)}{x^{3}+1}$

Simplifying:

$x-2$

Hence, the correct option is C. x-2

The sum of two numbers is 22 and their difference is 12 what are the numbers

nlexa [21]

Answer:

The numbers are 17 and 5

Step-by-step explanation:

x + y = 22

x - y = 12

Add y to both sides of the equation

x = 12 + y

Substitute new value for x into first equation

12 + y + y = 22

Add the y's

12 + 2y = 22

Subtract 12 from both sides

2y = 10

y = 5

22 - 5 = 17

The numbers are 17 and 5

Hope this helps :)

Quadrilateral ABCD has the following vertices.

Marizza181 [45]

A(-5,5)
B(4,5)
C(2,0)
D(-5,-2)

AB,BC,CD,DA

AB = [4-(-5)),5-5]=[9,0]
Lenght $AB= \sqrt{9^2+0^2}= \sqrt{81} =9$

BC = [2-4,0-5]=[-2,-5]
Lenght $BC=\sqrt{(-2)^2+(-5)^2}=\sqrt{4+25}=\sqrt{29}$

CD = [-5-2,-2-0]=[-7,-2]
Lenght $CD=\sqrt{(-7)^2+(-2)^2}=\sqrt{49+4}=\sqrt{53}$

DA =[-5-(-5),-2-5]=[0,-7]
Lenght $DA=\sqrt{0^2+(-7)^2}=\sqrt{49}=7$

sorted from longest to shortest:
AB, CD,DA,BC
$\sqrt{81}, \sqrt{53}, \sqrt{49}, \sqrt{29}$
