Answer: 
Step-by-step explanation:
For this exercise you need to use the following formula for calculate the area of regular polygon:
Where is "s" the length of any side, "n" is the number of sides.
Int this case you know that it is regular pentagon, which means that it has five sides. Then you can identify that the values of "n" and "s":
Therefore, substituitng values into the formula, you get that the area f the pentagon is:

Answer:
A
Step-by-step explanation:
It's a solid dot that's going left, so it's less than or equal to. What integer is it on? -2. So it is either less than or equal to -2.

Answer:
Last year's price was $12.50.
Step-by-step explanation:
We'll use the variable x to represent last year's price. First, we have to set up an equation:
.60x + x = 13.25
We get this equation because $13.25 is 6% MORE than last year's price, meaning we need to add the original price to the increase. Next, we combine like terms and solve for x:
.06x + x = 13.25
1.06x=13.25
1.06 r 1 .06 = 13.25 1.06
=$12.50
Last year's price was $12.50.
Really Hope This Helps :) Stay safe folks <3
