Answer:
DE = 15
DF = 23
Step-by-step explanation:
E___D___F
EF = DE + DF
38 = (3x +9) + (12x-1)
38 = 15x + 8
15x = 38 - 8
15x = 30
x = 30/15
x = 2
DE = 3x + 9 = 3(2) + 9 = 6 + 9 = 15
DF = 12x - 1 = 12(2) - 1 = 24 - 1 = 23

Answer:
it is a concave octagon
Step-by-step explanation:
A convex octagon has no angles pointing inward so in other words, the angles cant be acute. A concave octagon has angles pointing inward therefor it is a concave octagon.
The first thing I would do is to multiply everything by 3 to get rid of the fraction:
3M = 3wp + yp²
We can then take the 3M over to the other side to leave a quadratic equation:
yp² +3wp - 3M = 0
The easiest way to solve this for p is to use the quadratic formula:
p = <span>± (</span>√(9w²+12yM))/2y
