Do 36 divided by the amount of sides the hexagon has. I think I am not sure
Solution:
The given equation is

Now we will factor the middle term as per the ac-method because the given equation is a quadratic equation.

Answer:
-40s^2+8s+3
Step-by-step explanation:
use the foil method to multiply out 4s*-10s, 4s*-3, -10*-10s, and -10*-3 and then simplify
The original gross margin is (2.50 / 1.00) - 1 = (2.5 - 1) = 1.5 = 150%
the cost increases 0.25, is an increase of (0.25 / 1.00) = 25%
in order to keep the same gross margin, you need to increase the sale price by 25%
2.50*1.25 = 3.125
Then the gross margin is (3.125 / 1.25) - 1 = (2.5 - 1) = 1.5 = 150% ( same as original )
