The Pick's theorem
Let P be a polygon in the plane whose vertices have integer coordinates. Then the area of P can be determined just by counting the lattice points on the interior and boundary of the polygon!
In fact, the area is given by
where <em>i</em> is the number interior lattice points, and <em>b</em> is the number of boundary lattice points.
<em>Look at the picture</em>.
<em>i = 38</em>
<em>b = 14</em>
Substitute:
Answer:
x = 0
Step-by-step explanation:
The goal is to isolate x. For this equation, you need to distribute the -3 to the terms inside the parentheses first. Then, add both sides by 12. Finally, divide the 24 by -3 in order to finally isolate x.
Thus, x = -8.
