The vertex of the given parabola is the point (3, 25).
<h3>
How to get the vertex of the parabola?</h3>
If the parabola has roots x₁ and x₂, then the vertex of the parabola is at:
xₙ = (x₁ + x₂)/2
Here the parabola is:
y = (-2 - x)*(x - 8)
We can rewrite that to:
y = -(x + 2)*(x - 8)
Then the two roots are:
x = -2 and x = 8
Then the vertex is at:
xₙ = (8 - 2)/2 = 6/2 = 3
To get the y-value of the vertex, we evaluate the equation in x = 3:
y = -(3+ 2)*(3 - 8) = -5*(-5) = 25
The vertex is (3, 25).

It should be 40 because 180 is the full line and then 90 is taken by the right angle. And the vertical angle makes the other one 50 so the one your trying to find is 40.
<span>Tran is incorrect because he only has 1/3 of clay left. Noah as 2/4 or 1/2 left. 1/3 < 1/2 </span>
3k+14=k. Subtract 3k from both sides. 14= -2k. Divide both sides by -2. K=14/(-2)=-7. K is -7.
