What is the other solution??
Vladimir79 [104]

Answer:

The other solution is 12.

Step-by-step explanation:

Break the solution into groups: (x^2+2x)+(-12x-24)

Factor out the x^2 from the first group to get x(x+2)

Factor out the -12 out of the second group to get -12(x-12)

Here we get (x-12)(x+2)

You can see solutions are -2 and 12.

Vitek1552 [10]

Answer: 0.15(40) + 0.6(x – 40) = 0.25(x)

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:  

Fifteen percent of the pigment in paint color A is black

15% = 15/100 = 0.15 (decimal form)

0.15 A

Sixty percent of the pigment in paint color B is black

0.6 B

An unknown amount of paint color B is mixed with 40 ml of paint color A,

SO:

0.15 (0.40)  

0.6 (x-0.40)

x = total amount of paint in the mixture of the two colors

The result is a paint that contains 25% (0.25 in decimal form)black pigment (x)

0.15(40) + 0.6(x – 40) = 0.25(x)

Feel free to ask for more if needed or if you did not understand something.
