Answer:

Step-by-step explanation:
We can start by finding the third side of the triangle/the side of the square using the Pythagorean Theorem:

In this case the side length of the square would be represented by the variable "c" as it is the hypotenuse:




Since the area of a square is the side length square then...

The square root and the squared cancel out giving us...

Answer:
each ticket = $27.75
Step-by-step explanation:
70.50-15=55.50
55.50÷2=27.75
Answer: (0,-5), (5, 0), (10, 5) and (15,10).
Step-by-step explanation:
Given equation: 
To find its inverse we will find the value of x .
Subtract 5 from both sides

Switch y to x, we get
y= x-5, which is the inverse function.
At x=0,
y=-5
At x= 5,
y=0
At x= 10 ,
y=5
At x= 15,
y= 10
Hence, the four points contained in the inverse: (0,-5), (5, 0), (10, 5) and (15,10).
