I hope the choices for the numerators of the solutions are given.
I am showing the complete work to find the solutions of this equation , it will help you to find an answer of your question based on this solution.
The standard form of a quadratic equation is :
ax² + bx + c = 0
And the quadratic formula is:
x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}
So, first step is to compare the given equation with the above equation to get the value of a, b and c.
So, a = 10, b = -19 and c = 6.
Next step is to plug in these values in the above formula. Therefore,
So,
So,
Hope this helps you!
Answer:
The adult tickets cost $9 each. The child tickets cost $5 each.
X = $9 and Y = $5
Step-by-step explanation:

For the first one, do the same.
$9 x 3 = $27
$5 x 4 = $20
Add them and you get $47
Answer:
Step-by-step explanation:
Given
cosA = 
= 
Then the opposite side using Pythagorean triple is 4, thus
sinA = 
Using the trigonometric identity
sin2A = 2 sinAcosA, then
sin2A = 2 × ×
= 
=
