Euler's formula, V - E + F = 2 relates the number of vertices V, the number of edges E, and the number of faces F of a polyhedron. How many faces does a polyhedron with 5 vertices and 8 edges have?

12. x2 - 25 = 0 solve for square roots

How many solutions does the equation have? |p - 4| = - 5

F (x) = 2/3x+3, what is the value of f (12)

A problem on a multiple-choice quiz is answered correctly with probability 0.9 if a student is prepared. an unprepared student guesses between 4 possible answers, so the probability of choosing the right answer is 1/4.
