Answer:</h2>

<h2>
Step-by-step explanation:</h2>
A trapezoid is a quadrilateral where at least one pair of opposite sides are parallel. In a trapezoid, the both parallel sides are known as the bases of the trapezoid. So we have two bases, namely,
. Also, the height
of the trapezoid is the length between these two bases that's perpendicular to both sides. So the area of a trapezoid in terms of of
is:

Since:

The area is:

Answer:
h(x) = 1/2x + 5
Step-by-step explanation:
Switch the positions of the x and y (f(x)) and solve for y (f(x)).
f(x) = 2x - 10
x = 2y - 10
x + 10 = 2y
(x + 10)/2 = y
1/2x + 5 = y
