<span>The value of y when x=3 when the value of y varies directly with x^2, and y = 150 when x = 5 is 54. Since the value of y varies directly with x2, then: y = k * x^2, where k is constant. When y = 150 and x = 5, the value of constant is: 150 = k * 5^2. 150 = k * 25. k = 150/25. k = 6. Thus, when x = 3, the value of y will be: y = 6 * 3^2. y = 6 * 9. y = 54.</span>
Vertical angles are equal.
Therefore,
-x + 26 = 2x - 10
3x = 36
x =12
Therefore, angle D = 14 degrees.

Answer:
f(g(x)) = 2/(x^2 +4x)
Step-by-step explanation:
This would be a scalene triangle, because all of the sides are different lengths.
The correct answer is C.
