A solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
hope that helps
As they are similar corresponding sides are in the same ratio, so
18/15 = x / 4
x = 4*18 / 15
x = 4.8 answer
Answer:
<em>The slope of the line is -1</em>
Step-by-step explanation:
<u>Slope of a Line</u>
Suppose we know a given line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated as follows:

From the table in the image, we select the points (1,4) (3,2). The slope is:

Now select two other points like (5,0) (7,-2)

Following the same procedure with any other pair of points, we'll get the very same result:
The slope of the line is -1
