Answer: 
Step-by-step explanation:
10 pens - 2 pens = 8 pens
Write 8 of 10 as a fraction.
You get
, right?
Now, simplify 8/10.
You get 4/5.
2 becuae......................................................................................................you have 5/10
The gemstone has 22 edges.
We use Euler's formula on this:
F + V - E = 2
Substituting our information, we have:
14 + 10 - E = 2
Combining like terms,
24 - E = 2
Subtract 24 from both sides:
24 - E - 24 = 2 - 24
-E = -22
Divide both sides by -1:
-E/-1 = -22/-1
E = 22
Graph the inequalities given by the set of constraints. Find points where the boundary lines intersect to form a polygon. Substitute the coordinates of each point into the objective function and find the one that results in the largest value.
so you take the average of the x coordinates and the average of the y coordinates to get the midpoint like this
