Answer:
Option C is correct
point D is coplanar
Step-by-step explanation:
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>
If you mean each minute she read 3 pages.
If she started on page 20 and read 3 pages every minute, and the answer is how many pages did she read in 9 minutes.
Simple just do 20 x 9.
First step - what’s 2 x 9...18. Now anytime there’s a zero just simplify it by putting the 0 at the end of your answer. So the answer would be 180.
I hope this helped!!!
