18. By subtracting the areas of the two smaller triangles from the area of the large triangle, find the area of the quadrilateral ABDF?

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

600,000,000,000, or 6e14

step-by-step explanation:

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
