Find the number of possible 5-card hands that contain the cards specified (the cards are taken from a standard 52-card deck):
5 black cards
3 aces and 2 kings
2 face cards (kings, queens, or jacks) and 3 cards that are not face cards
5 red cards or 5 black cards
At most 1 ace

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

true
