   Use multiplication or division to solve for the variable.

Step-by-step explanation:

Solution

= −7

Step-by-step explanation:

3 + 9 = − 12

3 + 9 − 9 = − 12 − 9

Subtract the numbers

Subtract the numbers

3 = − 21

Divide both sides of the equation by the same term

3 = − 21

3/3 = −21/3

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
