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).

Answer:
There is not enough information to prove the congruence
Step-by-step explanation:
There is not enough information to prove the congruence because we would need to be given at least 3 equal elements (angles and sides) between the triangles. But in this problem we are only given the fact that 2 sides are equal in both triangles, which as I mentioned earlier is not enough.

Answer: 72 square inches
step-by-step explanation:
the equation for surface area is 2lw+2lh+2hw
breaking each of the sides down,
the length is 6 inches
the width is 2 inches
and the height is 3 inches
now substitute these into the equation
2(6)(2)+2(6)(3)+2(3)(2)
24+36+12
72 square inches
