Sendo V o número de Vértices, F o número de Faces e A o número de Arestas de um poliedro convexo, a relação de Euler pode ser equacionada como: A) V + F = A - 2 B) V + F = A + 2 C) V + F = A + 1 D) V + A = F - 1 E) V + F = A + 2

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

none.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
