A rectangle has 4 sides, so two sides would be equal to 12-m and 2 sides would be equal to 5-m.
All you have to do is add up the sides:
12 + 12 + 5 + 5 = 34-m
Slope formula : (y2 - y1) / (x2 - x1)
(4,1)...x1 = 4 and y1 = 1
(-1,-5)...x2 = -1 and y2 = -5
now we sub and solve
slope = (-5 - 1) / (-1 - 4) = -6/-5 = 6/5 <==
Step-by-step explanation:
y =kx(where k is constant)
18 = 6k
divide both side by 6
k = 6
The relationship between x and y
y = kx
y =3x
Apply the Pyth. Theorem:
c^2 = 3^2 + 7^2, or c^2 = 9 + 49 = 58. Thus, c = sqrt(58).
