I am assuming this is a triangle.....P = a + b + c
P = 2a - 3 + 2a + 3a + 1....combine like terms
P = 7a - 2 <==
The regular hexagon has both reflection symmetry and rotation symmetry.
Reflection symmetry is present when a figure has one or more lines of symmetry. A regular hexagon has 6 lines of symmetry. It has a 6-fold rotation axis.

Rotation symmetry is present when a figure can be rotated (less than 360°) and still look the same as before it was rotated. The center of rotation is a point a figure is rotated around such that the rotation symmetry holds. A regular hexagon can be rotated 6 times at an angle of 60°

Answer:
y = -3x + 18
Step-by-step explanation:
y = mx + b
m = -3
6 = (-3) * 4 +b
b = 6 - (-3) * 4
b = 6 +12
b = 18
y = -3x + 18
Answer:
Option D is correct.
Bimodal (Having two modes)
Step-by-step explanation:
- Symmetric distribution is a situation in which the values of variables occur at regular frequencies, and the mean, median and mode occur at the same point.
- In a negatively skewed distribution, the mean is usually less than the median because the few low scores tend to shift the mean to the left.
- In a positively skewed distribution, the mode is always less than the mean and median.
- A bimodal distribution is a continuous probability distribution with two different modes, that is, two different values with the highest and equal frequencies.
