Answer:

y = 2 \sqrt{6}

Step-by-step explanation:

\frac{y}{ \sin(60) }  =  \frac{4 \sqrt{2} }{ \sin(90) }  \\  \frac{y}{ \frac{1}{2} \sqrt{3}  }  =  \frac{4 \sqrt{2} }{1}  \\ y = 4 \sqrt{2} \times  \frac{1}{2}   \sqrt{3}  \\ y = 2 \sqrt{6}

(Apex!) Select the two values of x that are roots of this equation 3x-5=-2x^2
katovenus [111]

Answer:

B and D

Step-by-step explanation:

Write as a quadratic

-2x² - 3x + 5 = 0

Factor

-2x² - 5x + 2x + 5 = 0

-x(2x + 5) + 1(2x + 5) = 0

(1 - x)(2x + 5) = 0

To make the equation 0, x is either 1 or -5/2.
