Which expression and diagram represent “three times a number”?
3 x right-arrow 3 boxes with x and 3 boxes with minus signs
3 x right-arrow 3 boxes with x

3 + x right-arrow 2 boxes with x and 3 boxes with plus signs

x + 3 right-arrow 3 boxes with plus signs

answer:

i think this is the answer i not sure 3 + x right-arrow 2 boxes with x and 3 boxes with plus signs

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

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
