I am going to go with the assumption that your equation is
. If there is only one solution, then the equation must be a perfect square. So square
to solve for the equation in the similar form that is given.
. So the variables match up perfectly in the equation, meaning that the value of m is 6, letter choice C.
Half of the cards are red and half of them are black
so the answer is 1/2
or you can say that 26 are red and 26 are black
26/52 = 1/2
