Answer:
<h2>f(13) = 25</h2>
Step-by-step explanation:
f(x) = 2x – 1
To find f(13) substitute the value of x that's 13 into f(x). That is for every x in f (x) replace it with 13
We have
f(13) = 2(13) - 1
= 26 - 1
We have the final answer as
<h3>f(13) = 25</h3>

First, find the height of the trapezoid. Draw the height DE. Quadrilateral ABED is a rectangle, then BE = 12 cm. Since BC = 20 cm, then EC = 20 - 12 = 8 cm.
Consider right triangle DEC. By the Pythagorean theorem,
The area of the trapezoid ABCD is
