How would the expression x2 +8 be rewritten using Sum of Cubes?

Nadusha1986 [10]

Answer:

$x^3+8=(x+2)(x^2-2x+4)$

So if they meant $x^3+8$ then the answer is:

$(x+2)(x^2-2x+4)$ .

The choice this corresponds to is A.

Step-by-step explanation:

The sum of cubes formula for factoring or expanding:

$a^3+b^3=(a+b)(a^2-ab+b^2)$

You have I'm assuming they meant:

$x^3+8$ .

Compare $x^3+8$ to $a^3+b^3$ .

You should see in place of $a$ you have $x$ .

You should also see in place of $b$ you have $2$ .

$a^3+b^3=(a+b)(a^2-ab+b^2)$

$x^3+8$

$x^3+2^3$

$x^3+2^3=(x+2)(x^2-2x+2^2)$

$x^3+8=(x+2)(x^2-2x+4)$

Let's check it for fun.

So we are going to use the distributive property.

We are going to distribute all the terms in the first ( ) to all the terms in the second ( ).

$x(x^2-2x+4)$ + $2(x^2-2x+4)$

$x^3-2x^2+4x$ + $2x^2-4x+8$

Combine like terms:

$x^3-2x^2+2x^2+4x-4x+8$

Simplify the grouping of like terms:

$x^3+0x^2+0x+8$

0 times anything is 0:

$x^3+8$

Which of the following is not a condition of a Tessellation?

melomori [17]

The answer would be 1. Tessellation involves tiling and is a display of shapes fitted together on a surface, which means that tessellation does not only compose of one shape. It has to have a repeating pattern with no gaps. That can be achieved with a variety of shapes.

Given the triangle with angle a being 53° angle C being 58° what is angle B

sp2606 [1]

Sum measure interior angle = (n-2)180 ; n is the no.of sides

=(3-2)180

= 180°

53+59+x = 180

111+x = 180

x = 180-111

x = 69°
