40w - 8y + 16
-8 x -5w = 40w
-8 x y = -8y
-8 x -2 = 16

Answer:
Length of side AB = 5
Step-by-step explanation:
A regular polygon is one in which all angles are equal and all the sides have the same length.
Now, it means that;
AB = BC = CD = DE = AE
We are told that BC is represented by 3x - 4 while DE is represented by the expression 4x - 9.
Thus, from equal length of sides of a regular polygon, we have;
3x - 4 = 4x - 9
4x - 3x = 9 - 4
x = 5
Thus, length of BC = 3(5) - 4 = 15 - 4 = 11
Therefore, Length of AB = 5
Answer:
Step-by-step explanation:
3x - 7y + 12 = 5x - 9
-7y = 5x - 3x - 9 - 12
-7y = 2x - 21
7y = 2x + 21
y = 2/7x + 3
