The diagram shows part of the graph of y= x(x − 2)(x+1). Use the graph to solve each of the following inequalities
a x(x - 2)(x +1)<0,
b x(x-2)(x+1) > 1,
c x(x-2)(x+1) < -2.​

step-by-step explanation:

eww xbox also eww dayz

step-by-step explanation:

just for that im not answering

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

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
