Answer:
8
Step-by-step explanation:
The condition for the discriminant b² - 4ac is
If b² - 4ac > 0 then roots are real, irrational and unequal
If b² - 4ac > 0 and a perfect square, roots are real, rational and unequal.
Thus
b² - 4ac = 8

Greates to least, 45.947; 17.639; 3.828
Answer:
11.325 is what I got
Step-by-step explanation:
Exterior angles of polygons always add up to 360 degrees.
A pentagon has 5 sides, so divide 360 degrees by 5 sides.
360/5 = 72
One exterior angle of a regular pentagon (all 5 sides and angles are equal) is 72 degrees.
