Answer:
Eulers formula of course is: F+ V - E = 2, (F)aces + (V)ertices - Number of (E)dges = 2. Which he derived from solving the Koningberg Bridge problem.
I dont know if this will be of help: pentagonal prism https://en.wikipedia.org/wiki/Pentagonal_prism. it seems to fit what you are looking for!
Step-by-step explanation:
The answer is = (3-2)x4 = (3-2)=1, 1x4=4
B.
Because it reflects over
Answer:
(D). The number that is 7 to the right of 2 on the number line
Step-by-step explanation:
It could also be the number that is 2 to the right of 7 on the number line. When numbers are added, the distances of each to the origin are laid end-to-end from the origin to the right on the number line.
2+7 can mean that the distance 2 is added to the distance 7, or vice versa. (The commutative property of addition says order does not matter.)
2 + d = 2 - 3(d- 5) - 2
First, cancel 2 on both sides. / Your problem should look like:
Second, expand. / Your problem should look like:
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like:
Fourth, add 3d to both sides. / Your problem should look like:
Fifth, add d + 3d to get 4d. / Your problem should look like:
Sixth, divide both sides by 4. / Your problem should look like:
![d = \frac{13}{4}](https://tex.z-dn.net/?f=d%20%3D%20%20%5Cfrac%7B13%7D%7B4%7D%20)
