Answer:
- triangle
- square
- hexagon
- dodecagon
Step-by-step explanation:
The 12 points marked can be divided into this many equal-size groups:
3, 4, 6, 12
so the figures that can be constructed are ...
- triangle . . . . connects every 4th mark
- square . . . . . connects every 3rd mark
- hexagon . . . .connects every other mark
- dodecagon . . connects every mark
_____
12 is also divisible by 1 and 2, but the minimum number of vertices in a regular polygon is 3.

The formula of the sum of a geometric sequence:

We have:

substitute:

Answer: C. -5460
Answer:
$6.39
Step-by-step explanation:
Just add the cost of everything
3.18 + 1.25 + 1.96 = 6.39
Answer:
x = 21
Step-by-step explanation:
11x – 32 = 31 + 8x
11x = 63 + 8x
3x = 63
x = 21
For 2 it is slope 3 and y intercept (0,5)
For 3 it is slope y=-4x-5
