Answer:
The area of the regular pentagon is 
Step-by-step explanation:
we know that
The area of a regular polygon is equal to
where
P is the perimeter of the regular polygon
a is the apothem
Find the perimeter P
----> the regular pentagon has five equal sides
---> distance from center to middle of side
substitute
Answer:
C = 3.14... x d
Step-by-step explanation:
To calculate the circumference do pie times the diameter of the circle
Answer:
(52x + 1) - 3 • (5x + 1)) + 10 = 0
37x + 8 = 0
3.1 Solve : 37x+8 = 0
Subtract 8 from both sides of the equation :
37x = -8
Divide both sides of the equation by 37:
x = -8/37 = -0.216
x = -8/37 = -0.216
Answer:
No solution
Step-by-step explanation:
When we take the 5/2 x to the other side, 4x and 4x cancels out. We get 7=0 which is incorrect. Therefore, x has no solution.
