State the multiplicative identity property of one using the variable b.

Answer with Step-by-step explanation:

We are given that a variable b.

We have to state the multiplicative property  of 1.

Multiplicative identity property of 1:It states that when a number b is multiplied by 1 then we get number itself.

For example:

b=9

When a number is multiplied by 1 then we get number itself.This is called multiplicative identity property of 1.

i belive those are the ones that are under 90 degreese.

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
