Step-by-step explanation:
Written in standard form, the quadratic is ...
x^2 -2x -3 = 0
This can be factored as ...
(x -3)(x +1) = 0
so the solutions are ...
x = 3, x = -1 . . . . . . values of x that make the factors zero
The difference of interest is ...
3 -(-1) = 4

One of the game operators has designed a new game. In this game, players pick one card out of an ordinary deck of 52 playing cards. An ace wins $10, a face card (K, Q, or J) wins $1, and all other cards win nothing.
Answer:
x=4
Step-by-step explanation:
First, you need to isolate the variable and constant terms. So, we need to get rid of 36. To do this, we need to take away 36. Now, we have to do this on the other side. 64-36 is 28. Now, the equation is 7x=28.
To isolate the variable, you divide by 7. Again, do this on the other side. 28/7 is 4. Now we have x=4.
Therefore, the correct answer is 4!

C because you multiply the big number with the lower number then you add the number on top. 3 times 3 equals 9 plus 2 = 11. you keep the bottom number under your new number
