Answer:
<h3>Both are correct</h3>
Step-by-step explanation:
All the sides of an equilateral triangle are equal. Hence;
Perimeter of an equilateral triangle = 3S
S is one of the side length
Given;
S = 4n-2
Perimeter of the triangle = 3(4n-2)
This can also be expressed as P = S + S + S
P = (4n-2) + (4n-2) + (4n-2)
This shows that both methods are correct
$56.25, since 25% off can also be written as ÷4, since 25 is a quarter. 75÷4=18.75
75-18.75=56.25. Therefore, the answer is $56.25
Equal to, I think. Hope this helps.... If not sorry.
