Answer:

x = - 6, x = - 1

Step-by-step explanation:

\frac{2x}{x+2} = - \frac{6}{x+4} ( cross- multiply )

2x(x + 4) = - 6(x + 2) ← distribute parenthesis on both sides )

2x² + 8x = - 6x - 12 ( subtract - 6x - 12 from both sides )

2x² + 14x + 12 = 0 ( divide through by 2 )

x² + 7x + 6 = 0 ← in standard form

(x + 6)(x + 1) = 0 ← in factored form

equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

x + 1 = 0 ⇒ x = - 1

Answer:

It will not taste the same bc there is too much oj.

Step-by-step explanation:

The recipe is saying that for every 4 cups of pineapple juice you put in, you must put in 5 cups of orange juice.  That means if you put 8 cups of pineapple juice, you need 10 cups of orange juice, and if you have 12 cups of pineapple juice, you need 15 cups of oj.  Obviously, 15 is less than 20.  You are using too much oj, and because of this, it will not taste the same.
