Hendecagon has 11 sides,dodecagon has 12 sides,triskaidecagon has 13 sides,tetradecagon has 14 sides,pentadecagon has 15 sides,hexadecagon has 16 sides,17 sides is heptadecagon,octadecagon have 18 sides,enneadecagon has 19 sides,20 sides is called as icosagon. The prefix of that 9 polygons is Greek. A polygone with 4 sides is called a quadrilateral.
What is a 109 sided shape called?
109-gon. After about the first 10-20 or so shapes, they start referring to polygons as n-gons (where n is the number of sides).
How do you do the elimination method for 8x-y20 and -5x y-8?
If this is: 8x - y = 20 -5x = y - 8 8x - y = 20 -5x - y = -8 multiply by -1in order to eliminate y; 8x - y = 20 5x + y = 8 add both equations; 13x = 28 x = 28/13 substitute the value of x into the one of the equations in order to find y. For example, substitute it into the first one; 8(28/13) - y = 20 224/13 - y = 20 multiply both sides with 13; 224 - 13y = 260 224 - 224 - 13y = 260 - 224 -13y = 36 multiply both sides by -1; 13 y = -36 divide both sides by 13; y = -36/13 So the solution set is (28/13, -36/13) Check: 8(28/13) -(-36/13)= 224/13 + 36/13 = 260/13 = 20 -5(28/13) = -36/13 - 8 ? -140/13 = -36/13 -8 ? -140/13 = -36/13 - 8(13/13) ? -140/13 = -36/13 - 104/13 ? -140/13 = -140/13

3x plus 6 equals 5x-20 what is x?
3x + 6 = 5x - 20 Subtract 3x from both sides: 6 = 2x - 20 Add 20 to both sides: 26 = 2x Divide both sides by 2: 13 = x
