1. Which polygon or polygons are regular?
A regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
Therefore your answer is:
A. equilateral triangle
C. square
2. Which polygon is always irregular?
traingle - NOT (equilateral triangle)
trapezoid - YES
square - NOT
hexagon - NOT (regular hexagon)
Answer:
12 : 4.92
Step-by-step explanation:
a= apples
12a=4.92
12 : 4.92
You should scan it on this app:)
1. 1st transformation is translation the parent function 
6 units to the right to get the function 
2. 2nd transformation is reflection the function 
over the x-axis. This transformation gives you the function 
3. 3rd transformation is vertical stretch of the function 
by a factor of 2 to get the function 
Only last two are present in options, then
answer: C and D.
