B. slope is -1/2
This is because the m-value aka the slope is always the reciprocal if the line is perpendicular
-0.7166666666666666 that is the answer I got but can be rounded to -0.72
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
