Answer:
-16 i sqrt(3) + 207
Step-by-step explanation:
Simplify the following:
(2 i sqrt(48) - 3) (-4 i sqrt(12) - 5)
sqrt(12) = sqrt(2^2×3) = 2 sqrt(3):
(2 i sqrt(48) - 3) (-4 i×2 sqrt(3) - 5)
-4×2 = -8:
(2 i sqrt(48) - 3) (-8 i sqrt(3) - 5)
Factor -1 from -8 i sqrt(3) - 5:
(2 i sqrt(48) - 3)×-(8 i sqrt(3) + 5)
sqrt(48) = sqrt(2^4×3) = 2^2 sqrt(3):
-(2 i×2^2 sqrt(3) - 3) (8 i sqrt(3) + 5)
2^2 = 4:
-(2 i×4 sqrt(3) - 3) (8 i sqrt(3) + 5)
2×4 = 8:
-(8 i sqrt(3) - 3) (8 i sqrt(3) + 5)
-(8 i sqrt(3) - 3) = -8 i sqrt(3) + 3:
-8 i sqrt(3) + 3 (8 i sqrt(3) + 5)
(-8 i sqrt(3) + 3) (8 i sqrt(3) + 5) = 3×5 + 3×8 i sqrt(3) + -8 i sqrt(3)×5 + -8 i sqrt(3)×8 i sqrt(3) = 15 + 24 i sqrt(3) - 40 i sqrt(3) + 192 = -16 i sqrt(3) + 207:
Answer: -16 i sqrt(3) + 207
Answer:you can't factor a prime number!!! You really should read the book, then you have a chance on the final when you don't have access to Y!A.

Answer:
Point, Line, and Plane
Step-by-step explanation:
The three undefined terms that form the basis for the subject are a point, a line, and a plane. A point is basically like a dot, which most people should know. A line is a straight one dimensional figure that extends to infinity in both directions. A plane a flat 2 dimension figure, that extends to infinity in all directions. You can think of a plane as infinite lines put next to each other.
You can visualize a point, a line, and a plane in a coordinate grid. A point on the coordinate grid is any point, from (0, 0), the origin, to (2039, pi). A line on the coordinate grid is linear. It can be of any equation from y=x to y=238490/239x + 123. You can think of a plane as the entire coordinate grid.
