Answer:
top left choice
Step-by-step explanation:
the slope is negative, so its flipped
the y int is -6, below the x axis
Answer:
x³ + x² − 4x + 6 = 0
Step-by-step explanation:
Imaginary roots come in conjugate pairs. So if 1+i is a root, then 1−i is also a root.
(x − (-3)) (x − (1+i) (x − (1−i)) = 0
(x + 3) (x² − (1+i) x − (1−i) x + (1+i) (1−i)) = 0
(x + 3) (x² − x − ix − x + ix + 1 − i²) = 0
(x + 3) (x² − 2x + 2) = 0
x (x² − 2x + 2) + 3 (x² − 2x + 2) = 0
x³ − 2x² + 2x + 3x² − 6x + 6 = 0
x³ + x² − 4x + 6 = 0
Area A of a square with side length a: A = a².
Pythagoras theorem: a² + b² = c²
2*a² = 8²
A = 8²/2
The answer is 12a3 + 2a + 23a + 18
