How can the sum of cubes, x^3 - 27, be written in factored form? (x+3)(x^2+3x+9) (x+3)(x^2-3x+9) (x-3)(x^2+3x+9) (x-3)(x^2-3x+9)

(x -3)(x² +3x +9)

Step-by-step explanation:

The sum of cubes is factored as ...

... a³ + b³ = (a +b)(a² -ab +b²)

For a=x, b=-3, this is ...

... x³ -27 = (x -3)(x² +3x +9)

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

answer: b
