The correct answer is C) 12
Euler's formula states that the number of vertices subtracted by the number of edges and added to the number of faces of a polyhedron always equals 2:
V - E + F = 2
We have 24 edges and 14 faces:
V - 24 + 14 = 2
Combining like terms,
V - 10 = 2
Add 10 to both sides:
V - 10 + 10 = 2 + 10
V = 12
Bro copy the whole problem and paste it in brainly you’ll get the right answer works every time !!!!
Here is the answer
4(2a+3b)(2a-3b)
Answer:
(pound-feet)
Step-by-step explanation:
Given that:
Torque = r × F
Where ; r = radius in feet ; F = force in pounds
Hence, a possible unit measure of torque using the units provided for both force and Radius will be :
r (feet) × F (pounds) = Torque (pound-feet)
Hence, the possible unit of measure of torque = (pound-feet)
Other unit measure may be :
r (metres) × F(Newton) = Torque (newton-metre)
B is correct
12/3=4
-> 3 x 4 = 12
