All of the following represent the same set of numbers except natural numbers whole numbers positive integers counting numbers

Let us define each :

1. Natural numbers : the positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.

2.Whole numbers: Whole Numbers are simply the numbers 0, 1, 2, 3, 4, 5, ... (and so on)

3. Positive integers: The positive integers, z+ , consist of the whole numbers beginning with one.

4. Counting numbers: Any number you can use for counting things: 1, 2, 3, 4, 5, ... (and so on). Does not include zero.

So we can say that whole numbers is the odd one out, since it includes 0 and others dont.

i think the answer is seven, for if i'm being useless °ω°

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
