<u>Perimeter of a Triangle
</u>
Given a triangle of sides a,b,c. The perimeter is the sum of its sides, i.e.
P=a+b+c
The triangle shown in the figure has sides of values x+3, 2x-1, 3x-5. The perimeter is
P=x+3+2x-1+ 3x-5
Joining like terms:
P=6x-3 units
Correct answer: Third option

Using Hooke's Law ()
We need to find the spring constant of the bungee cord with the given extension and force, we can do this by substituting in known values.
Now we have found the spring constant of the bungee cord, we can substitute it in for the a different force. As the cord is the same we can use the same spring constant.
5x+12-2x= 15 Answer: (1,10)
x= 1
y=12-2(1)
y= 10
Answer:
Diameter of the pipe ≈ 6.77 ft
Step-by-step explanation:
Volume of a cylinder = πr²h
Here, r = Radius of the cylindrical pipe
h = Length of the pipe
Volume of the pipe = 900 ft³
Length of the pipe = 25 ft
By substituting the given values in the formula,
900 = π(r)²(25)
r² = 
r = √11.459
r = 3.385
Diameter = 2(radius)
= 2(3.385)
= 6.77 ft
