Factor the expression. x^3+8

1 answer:

3 0

X^3+8
= x^3+2^3

<span>a^3 + b^3 = (a + b)(a^2 – ab + b^2)</span>

so

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

A. m = 0 || This is incorrect, because m being equal to 0 is a solution in and of itself.

B. m = m || This is incorrect, because m being equal to itself means that there are an infinite number of solutions.

C. 2m + 1 = m - 2 | m = -3 || This is incorrect, because m can be solved for and has a solution.

D. m + 4 = m - 4 | 4 = -4 || This is correct because 4 is not equal to -4, and thus there is no solution.

Hope this helps!! :)

Yes, because 1+1+1=3 and those are the whole numbers and than 1/2+1/4 + 1/4=100 which is 4/4! And a whole!

Answer:

X =6

Step-by-step explanation:

Angles on a straight line add up to 180°

180-110=70

The 70° is the same on the angles above

70+8+17x=180

180-70=110

110-8=102

102/17=6

X=6

10^6 = 10 *10*10*10*10*10 = 1,000,000

10^2 = 10*10 = 100

1000000/100 = 10,000 times larger
