Given:
Side length = 12 in
To find:
The area of the regular polygon.
Solution:
Number of sides (n) = 6
Let us find the apothem using formula:

where s is side length and n is number of sides.




Area of the regular polygon:




in²
The area of the regular polygon is 374.1 in².
The given expression is :
2xx+3-5(x-2)
We know that, 

Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
Answer:
450+70x
Step-by-step explanation:
x is the number of months and 450 is the actual amount of money in his bank account
K = LMN
We divide both sides by LN:-
M = K / LN
