Hello!
So, we know that the length of the rectangular basketball court is 84 ft, and the width is 50 ft. 
The formula for perimeter of a rectangle is: 
P = 2l + 2w
This means that we need to multiply the length by two and the width by two as well. 
Substitute: 
P = 2(84) + 2(50)
P = 168 + 100 
P = 268 ft 
ANSWER: 
The perimeter of the basketball court is 268 feet long.
        
             
        
        
        
This is what I got pls mark me brainlest
 
        
        
        
Steps to solving equations:
Simplify/combine the like terms
Isolate the variable (Get the variable on one side
Solve for the variable
-2y - 7 + 5y = 13 - 2y Simplify/Combine terms
3y -7 = 13 - 2y Isolate variable by adding 2y to both sides
5y - 7 = 13 Add 7 to both sides to get y alone on one side
5y = 20 Divide by 5 on both sides to solve for y
y = 4
You can check your answer by replacing y with 4 in the original equation. 
        
                    
             
        
        
        
 Answer:
The graph of this piece-wise function is attached below.
Step-by-step explanation:
Given the function
 
 
- A piece-wise function is a function which has multiple pieces. 
- Each of the pieces have their own restrictions. 
- The domain of a function is the set of input, or x, values for which the function is defined. 
- The range is the set of all values taken by the function
As the piece
 has the domain [-5, 3) and graph of this piece is attached below.
 has the domain [-5, 3) and graph of this piece is attached below.
and 
 has the domain [3, 7) and graph of this piece is attached below.
 has the domain [3, 7) and graph of this piece is attached below.
So, the domain of the piece-wise function can be composed as [-5, 3) U [3, 7) and range has the interval ![\:\left[-1,\:27\right]](https://tex.z-dn.net/?f=%5C%3A%5Cleft%5B-1%2C%5C%3A27%5Cright%5D) .
.
i.e. 
Domain: [-5, 3) U [3, 7)
Range: ![\:\left[-1,\:27\right]](https://tex.z-dn.net/?f=%5C%3A%5Cleft%5B-1%2C%5C%3A27%5Cright%5D)
The graph of this piece-wise function is attached below.
