6x² + 6x - 12 = 6(x² + x - 2) = 6(x² + 2x - x - 2)

= 6(x·x + 2·x - 1·x - 1·2) = 6[x(x + 2) - 1(x + 2)]

= 6(x + 2)(x - 1)

6x² + 6x - 12 = 6(x + 2)(x - 1)

Solutions 

6x^2 + 6x - 12 = 6(x^2 + x - 2) = 6(x^2 + 2x - x - 2)


= 6(x*x + 2*x - 1·x - 1*2) = 6[x(x + 2) - 1(x + 2)]


= 6(x + 2)(x - 1)


6x^2+ 6x - 12 = 6(x + 2)(x - 1)

You need 112 K-cups for a party. A box of K-cups costs $16 for 36 K-cups. What is the minimum amount of money you will spend?
makkiz [27]

Answer:

$49.60

Step-by-step explanation:

The equation setup I used for this was as follows: $16 x (112/36)

Using PEMDAS, you'd start with the division part, 112/36. Although, I did this a bit differently, and being a bit further in school, I don't know if you go through this where you're at.

Start by factoring 112 into 4(28). This leaves you with 4(28)/36.

Next, cancel 4 out of 36. Since 4 is the common factor in 28 and 36, you cancel the four out of the equation, leaving you with 28/9. Convert this to its decimal form, 3.1.

Finally, take the 3.1 and multiply that by $16, which comes out to $49.60.
