x³ = 8
x³ - 8 = 0
a=x b=2
a³ - b³ = (a - b)(a² + ab + b²)
x³ - 8 = (x - 2)(x² + 2x + 2²)
(x - 2)(x² + 2x + 2²) = 0
(x - 2) = 0, (x² + 2x + 4) = 0
x = 2
x =
x =
Answer: the complex roots of 8 are: 2, -1 + √3i, -1 - √3i
So the answers I got are:
D. 8
E. 15/2
F. 16/3
Answer:
360
Step-by-step explanation:
Multiply them all
Answer:
Using the slope intercept formula, we can see the slope of line p is ¼. Since line k is perpendicular to line p it must have a slope that is the negative reciprocal. (-4/1) If we set up the formula y=mx+b, using the given point and a slope of (-4), we can solve for our b or y-intercept. In this case it would be 17.
