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>
Multiply the first bracket by 6.
Multiply the second bracket by 8
6(x+1)-5x= 8+2(x-1)
6(x)+6(1)-5x= 8+2(x)+2(-1)
6x+6-5x= 8+2x-2
6x-5x+6= 8-2+2x
x+6= 6+2x
Move +2x to the other side. Sign changes from +2x to -2x.
x-2x+6= 6+2x-2x
-x+6= 6
Move +6 to the other side. Sign changes from +6 to -6.
-x+6-6= 6-6
-x=0
Multiply by -1 for -x and 0
-x(-1)= 0(-1)
x= 0
Answer: x= 0
