Answer: b is the answer
Step-by-step explanation:
The area is when you muliply base×hight wich is 17×8.5=144.5 then divide by 2 so 144.5÷2=72.25
perimeter is when u add all sixes so its 17+8.5+19=44.5
P=44.5
Answer:

Step-by-step explanation:
Let
n ----> represent the number of tickets purchased
y ---> the total cost for a visit to the carnival in dollars
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The unit rate or slope is equal to

The y-intercept is equal to the cost for enter (value of y when the value of x is equal to zero)

substitute

For n=20 tickets
substitute the value of n and solve for y
