Answer:

x^{3} +2^{3}=(x+2)(x^{2} -2x+2^{2} )

Step-by-step explanation:

The general expansion of a polynomial of type a^{3} +b^{3} is given as follows:

a^{3} +b^{3} =(a+b)(a^{2} -ab+b^{2} )

Given polynomial is x^{3} +8

This can be written as x^{3} +2^{3}, which is of the form  a^{3} +b^{3}.

So we can use the general form to expand this polynomial where;

a→x

b→2

x^{3} +2^{3}=(x+2)(x^{2} -x\times2+2^{2} )

x^{3} +2^{3}=(x+2)(x^{2} -2x+2^{2} )

What is an equation of the line that passes through
lys-0071 [83]

Answer:

B

Step-by-step explanation:

For the perpendicular of an equation you need to flip the fraction and change the sign from positive to negative or if it's negative to positive. 3/2 is changed to -2/3 which when multiplied by -2 gives you 4/3 and 4/3+5/3 is equal to 3.
