___
/ ___ \ Let's imagine a trapezoid looks like this. The two parallel lines would be the top and the bottom lines.
The 10 in. side would be either the top or bottom line. The other parallel line is twice as long, meaning it's 2 times longer. So you multiply 10 in x 2 = 20 in.
The given side length = 10 inches.
Height = half as long, meaning it's half of 10 in. = 5 in.
Formula of a trapezoid =
x height
Where a and b are bases. The top and bottom of the trapezoid are bases.
Area trapezoid =
x 5 =
x 5 = 15 x 5 = 75 in² <-- area means the unit is squared
Considering the parabolic equation, the equation for the directrix is given by x = 4.9375.
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a horizontal quadratic function, of vertex (h,k), is given by:
(y - k)^2 = 4p(x - h)
The directrix is given by:
x = h - p.
In this problem, the equation is given by:
(y - 2)² = 0.25(x - 5).
Hence h = 5, p = 0.25/4 = 0.0625, hence the directrix is:
x = h - p = 5 - 0.0625 = 4.9375.

Answer:
41
Step-by-step explanation:
-(-8) = 8 and
-(-14) = 14
so, 19 + 8 + 14 = 41
