Answer:

Cocoa of Arjun's brother is more chocolatey

Step-by-step explanation:

Please edit your automated transcription before posting.

Please <em>double check</em> if the following interpretation corresponds to the original question.

When Arjun makes hot cocoa, he adds 20 mL of chocolate syrup for every 3 ounces of hot water.

Arjun's brother, Eli, adds 45 mL of chocolate syrup for every 6 ounces of hot water.

Which hot cocoa is more chocolatey?

1 oz. fl = 28.35 mL.

Arjun:

Total liquid = 20 + 3*28.35 mL = 105.05 mL

percentage of chocolate = 20/105.05 = 19.0%

Brother:

Total liquid = 45 + 6*28.35 mL = 215.1 mL

percentage of chocolate = 45/215.1 = 20.9%

Conclusion: Cocoa of Arjun's brother is more chocolatey

Answer:

  3(x)(4x -3)(2x -5)

Step-by-step explanation:

First of all, recognize that all coefficients are multiples of 3, and all terms have x as a common factor. This means your first factorization is ...

  (3x)(8x^2 -26x +15)

Now, you can use the "X-method" or similar to factor the quadratic. Start by looking for factors of (8)(15) = 120 that have a total of -26. Both will be negative. Here is a list of the positive factor pairs.

  120 = 1·120 = 2·60 = 3·40 = 4·30 = 5·24 = 6·20 = 8·15 = 10·12

The sums of these factor pairs are ...

  121, 62, 43, 34, 29, 26, 23, 22

The pair with a sum of 26 is highlighted.

Using this information, you can complete the X-method diagram, or you can use these numbers to rewrite the quadratic x-term to have 2 parts:

  8x^2 -20x -6x +15

Now, the quadratic can be factored by grouping:

  =  (8x^2 -20x) +(-6x +15)

  = 4x(2x -5) +3(-2x +5)

Recognizing the sign difference between the parentheses contents, we can factor the quadratic to be ...

  = (4x -3)(2x -5) . . . . . note the sign gets attached to the 3

So, the complete factorization of the original expression is ...

  24x^3-78x^2+45x = 3(x)(4x -3)(2x -5)
