Which number in the monomial 125x18y3z25 needs to be changed to make it a perfect cube?

has to be changed.

Step-by-step explanation:

The given monomial is .

If we see the separate terms of the monomial then we find that each term can be written in perfect cube form except z.

125 = 5³

y³ is in cube form

is the only term which can be written in the perfect cube form if it is or

So the answer is

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

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
