Answer:
the formula for a function d(x) that describes the distance is 
Step-by-step explanation:
We are going to define final point
, and initial point
, then we can use
, so we obtain
, by developing it 
This formula describes the distance between those two points and involves x
-81=3(5-4r)
27=-(5-4r)
27=-5+4r
-4r=-5-27
-4r=-32
r=8
Hope my answer helped u :)

ur welcome kid
check the picture below.
so the area of the rectangle is x*y.
the area of the triangle is (1/2)(w)(z).
if we subtract the area of the triangle, from the containing rectangle, we're in effect making a whole in the rectangle, as you see there in lower-right corner.
