Answer:

$\large\boxed{(2x+3)(4x^2-6x+9)}$

Step-by-step explanation:

$8=2^3\\\\8x^3=2^3x^3=(2x)^3\\\\27=3^3\\\\8x^3+27=(2x)^3+3^3\qquad\text{use}\ a^3+b^3=(a+b)(a^2-ab+b^2)\\\\=(2x+3)\bigg((2x)^2-(2x)(3)+3^2\bigg)=(2x+3)(4x^2-6x+9)$

Answer:

y = -1/2x

Step-by-step explanation:

The y - intercept is 0, because the point where the line touches the y - axis is y - value of 0

The slope is -1/2 because as it rises by -10, it runs by 20

Slope is rise/run which is -10/20 which simplifies to -1/2

y = mx + b

b = y - intercept

m = slope

y = -1/2x + 0 or y = -1/2x

If my answer is incorrect, pls correct me!
