Carl can rake his lawn in 6 hours his friend demetri can rake along the same size and just 4 hours if they work together to rake Carl's lawn what rational equation represents the information presented in this problem how long does it take them to rake the lawn to together

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

the answer is c hope this
