A swimming pool is 8 meters long 6 meters wide and 2 meters deep the water resistant paint need for the pool cost $6 per square meter how much will it cost to paint the pool a. how many faces of the pool do you have to paint ?

b. how much paint ( in square meters) do you need to paint the pool ?

c. how much will it cost to paint the pool ?

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

i believe that the answer is

b. y-1=-2(x-4)

hope this !
