Answer:
The answer is that the turning point, or vertex is: (4, 19)
Step-by-step explanation:
Given:
x^2 + 8x + 3
Separate out the first two terms with parenthesis:
(x^2 + 8x) + 3
Add 16 to complete the square, in the parenthesis and to the constant:
(x^2 + 8x + 16) + 3 + 16
Reduce:
(x + 4)^2 + 19
This is in the form:
(x + p)^2 + q
The vertex is at: (4, 19)
The area of a trapezoid can be found with this formula:
![A=\frac{1}2(b_1+b_2)h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D2%28b_1%2Bb_2%29h)
Where b1 and b2 are the bases and h is the height.
If we plug in what we know we can solve for the height.
We know that b1 = 52, b2 = 42, and A = 1833. Let's solve.
