What is equizelent to -15x + 39?

-3(5 x-13)

Step by step:   This is actually a common factor which also is your answer to this

5/6

step-by-step explanation:

if i remember correctly with perpendicular stuff you just take away the negative

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
