Answer
131ft^2
Step-by-step explanation:
I find area by basically taking the figure and making it into two figures and solving the area for the two then adding them up.
The easiest way to find a parallel equation is to write your equation in slope-intercept form. The general equation for slope-intercept form is y = mx + b, where m = the slope of the equation, b = the y intercept, and x and y are your variables.
You're given 5x + 10y = -4.
1) Move 5x to the right side by subtracting 5x from both sides:
5x + 10y = -4
10y = -5x - 4
2) Divide both sides by 10 to get y by itself on the left. Simplify:

<span>Remember that for
parallel lines, the slope, m, is the same for both equations. You can make the y-intercept, b, whatever number you want.
When the equation is in slope-intercept form, </span>

, you can see that

.
A parallel equation is in the form:

Plug in anything you want for b. One example is:

(just one example)
If each math book is 0.75 of a inch wide you would do 18 divided by 0.75= 24. 24 books width can fit into the 18 inches.

Answer:
352 ft²
Step-by-step explanation:
The formula for the area of a trapezoid is
where
and
are the bases of the trapezoid and
is the height, thus:

This means that the area of the trapezoid is 352 ft².
