Answer:
Two dimension
Step-by-step explanation:
In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space.
A plane is 2 dimensional.
For example a rectangles is a plane - it has length and width.
0.2c-c
SLOPE = -5
Because that's what x is.
The answer to this problem is 3(2x+1)
