A <u>trapezoid</u> is a quadrilateral with exactly one pair of parallel sides.
Formula for area: 
In this formula, the bases are the parallel sides.
Now plug the information into the formula.
.
Follow your order of operations, simplify inside the parentheses first.
.
(1/2)(8) is 4 so we have (4)(9) which is 36.
So the area of the trapezoid is 36.
Answer:
3/8
Step-by-step explanation:
The expression can be rewritten as b + 1/8 + c
substitute b and c
2 + 1/8 - 7/4 = 16/8 + 1/8 - 14/8 = 3/8
Answer: The campers will be
from their car after 12 hours.
Step-by-step explanation:
<h3>
The missing graph is attached.</h3>
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" the y-intercept.
We can pick two points on the line graphed and substitute the coordinates into this formula to find the slope:

Choosing the points (0,4) and (2,10), we get:

We can susbstitute the point (0,4) and the slope into
and solve for "b":

Then, the equation of this line is:

Since the distance in miles is represented on the y-axis and the time in hours is represented on the x-axis. we can rewrite the equation as:

Finally, in order to calculate the distance in miles that the campers will be from their car after 12 hours, we need to subsitute
into the equation and evaluate. Then we get:
