D. 127
...............
- square
- regular pentagon
- regular hexagon
- regular octagon
- regular nonagon
- regular dodecagon
The regular polygons could be used to make regular and semi-regular tessellations are equilateral triangle, square and regular hexagon. Therefore, the correct answers are A, B and D.
A regular tessellation is tessellation made up by using only one type of regular polygon. These are made up of completely congruent regular polygons all that connecting vertex to vertex.
Regular polygons have congruent straight sides. When we slide or rotate a regular polygon, the side of the original figure and the side of its translation will match.
Equilateral triangles, squares and regular hexagons are the only regular polygons that tessellate. Therefore, there are only three regular tessellations.
Therefore, the correct answers are A, B and D.

B. square
D. regular hexagon
E. regular octagon
G. regular dodecagon
Step-by-step explanation:
3x3 + 9x2 - 12x
If you factor 3x from the expression, you have
So, we have
We easily have
So, one solution is x=0.
The other solutions depend on the quadratic equation:
So, the solutions are
A.The first term is 25. Each term is multiplied by 5. The next 2 terms are 32,000 and 160,000.
B.The first term is 25. Each term is multiplied by 4.
The next 2 terms are 25,600 and 102,400.
C.The first term is 25. Each term is multiplied by 4.
The next 2 terms are 2560 and 10,240.
D.The first term is 25. Each term is multiplied by 5.
The next 2 terms are 3200 and 16,000.
Answer:
Firstly, when the manager lowered the $60 boot by 10%, the boot then became $54. Then, when the manager raised the boot again by 6%, we can find the new price by doing $54 multiplied by 0.06. This gave us $3.24. We then add this amount to our $54 total to get $57.24. Therefore, the new price is $57.24.
Step-by-step explanation:
4x + y = 15
x = 2, y = 7
x = -13, y = 7
x = - 2
3 , y = 12 2
3
x = 5, y = 1
