<em><u>The formula for a regular polygon is:</u></em>
<em><u /></em>
→ p is the perimeter and a is the apothem

105
A. 1 because a to b is 5 miles and b to c is 4 miles so it couldn't be 1 mile
One dozen = 12
15/12 = 1.25
The cost of one fruit tart is $1.25
2+4a=-10
First, subtract 2 from both sides.
4a=-12
Then divide 4 from both sides.
a=-3
