Slope of AB=(2-3)/(1+1)=-1/2; AC=(-1-3)/(-3+1)=-4/-2=2; BC=(-1-2)/(-3-1)=-3/-4=3/4.
The product of two sides that are perpendicular is -1. Slopes of AB and AC are perpendicular so angle A is a right angle. ABC is a right-angled triangle.
Given:
The equation is
To find:
The coefficient and reciprocal.
Solution:
We have,
Here, 
is multiplied with x.
So, the coefficient of x is .
To find the reciprocal, we need to interchange numerator and denominator of a fraction.
So, the reciprocal of is 
Therefore, the reciprocal is 3.

Answer:
a) 54 m is your answer
Step-by-step explanation:
Given: s = 9
The formula given is:
P (Perimeter) = 6s
Plug in 9 for s
P = 6(9)
Multiply.
P = 6(9)
P = 54
