Well, a polygon is just a generic shape. Triangle, Quadrilateral, Pentagon,Hexagon, Octagon, Decagon, etc. Sides are the lines that meet to make up the polygon, and vertices are the corners where the sides meet. Here are some examples:
<span>Triangle Quadrilateral (square, rectangle) </span>
<span>3 sides 4 sides </span>
<span>3 vertices 4 vertices </span>

Answer:
Slope of line 1 = 3
Slope of line 2 = 3
Slope of line 3 = -1/3
Line 1 and 2 are parallel
Line 1 and 3 are perpendicular
Line 2 and 3 are perpendicular
Step-by-step explanation:
Find the slope of each line by using this equation:
lines are parallel if they have the same slope and line are perpendicular in they have opposite reciprocal slopes. (-1/3 is the opposite reciprocal of 3).
Hope this helps!
Answer:
See below
Step-by-step explanation:
Tariku in second grade read 6 books each month during the year. This is equal to 6(12) = 72.
Tariku in third grade read 8 books each month during the year. This is equal to 8(12) = 96.
You can find the total amount with any of the below equations:
- 6(12) + 8(12)
- 12(6+8)
- 12(14)
For a total number of months x the equations would be the same except with x instead of 12.
Y=x2-1 is not a linear equation only because for it to be an linear equation it would have to be 2x-1=y or y=2x-1
