Answer:

Step-by-step explanation:
Comparing it with quadratic equation
, we get:
a = 1 . b = 4 and c = 5
So,
Discriminant = 
D = (4)²-4(1)(5)
D = 16 - 20
D = -4
Hence,
Discriminant = -4

Answer: 172 square centimeters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a pentagon (A) = 1/2× 5s × a
Where:
s : side of the pentagon
a: apothem
Replacing with the values given and solving for A (area):
A =1/2 x (5 x10) x 6.88
A = 172 square centimeters.
