Answer:

The solutions are x = -7, 6.

Step-by-step explanation:

To find the solutions, move everything to one side of the equation so the equation is equal to 0. Then factor. Set the factors equal to 0 and solve for x.

x^2 + x - 30 = 12\\x^2 + x -42=0\\(x+7)(x-6) = 0

x+7 = 0

x = -7

and

x-6 = 0

x = 6

The solutions are x = -7, 6.

You randomly choose one of the tiles. Without replacing the first tile, you choose a second tile. Find the probability of the co
Volgvan
Choosing the first tile:

At first, there are 7 tiles.
You are interested in choosing a 5. There is only one tile with a 5.
p(5) = 1/7


Choosing the second tile:
After the 5 has been taken, now there are 6 tiles left.
Only one tile has the number 6.
p(6) = 1/6

The overall probability of choosing a 6 after a 5 is the product of the individual probabilities:

p( 5 then 6) = 1/7 * 1/6 = 1/42

Answer: The probability of choosing a 5 and then a 6 is 1/42.
