If you would like to simplify the following expression <span>(28x - 7y) + (32x + 52y), you can do this using the following steps:
</span>(28x - 7y) + (32x + 52y) = <span>28x - 7y + 32x + 52y = 28x + 32x - 7y + 52y = 60x + 45y
</span>
The correct result would be B. <span>60x + 45y.</span>
The answer is A. 16 edges
Euler's polyhedron formula:
f + v - e = 2
f - the number of faces
v - the number of vertices
<span>e - the number of edges
</span>
f = 5 congruent <span>squares + 4 congruent equilateral triangles = 9
v = 9
e = ?
f + v - e = 2
e = f + v - 2
e = 9 + 9 - 2
e = 16</span>
