Lines of symmetry in regular polygons can be formed from a vertex to an opposite vertex or a vertex to an opposite midpoint.
The equation 
equals to 
Step-by-step explanation:
We need to solve the equation:
Solving:
Adding 9 on both sides
Applying absolute rule: |u| < a and a > 0 then, -a < u < a
So, 
Now we have,
m-8>-9 and m-8 <9
m>-9+8 and m <9+8
m>-1 and m<17
Combining the intervals:
-1 < m < 17
So the equation equals to

Answer:
an 12-1.5n
Step-by-step explanation:
Answer:
1 / We have the area of a rectangle ABCD = 8 x 16 = 128 ft²
2 / Find the area of an isosceles Δ DEF:
The base of the isosceles ΔDEF => DF = DC- FC = 16 -12 = 4 ft
So the area of Δ DEF = 1/2 (DF x EH) = 1/2 (4 x 6) = 12 ft²
3 / Area of the irregular shape = area ABCB + Area DEF = 128 + 12 = 140 ft²
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
girl honestly how does this question even come up
anyways you do 12 divided by 4 to get 3
