Benjamin visited an art show and saw a painting he really wanted to purchase but it was very expensive! In the gift shop, he found out he could buy post cards of the paintings at a much more affordable price. The post card was 4 inches by 6 inches and it said it was 2/7 of the size of the original. What are the dimensions of the original painting

answer: 1 + 1 = 11

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

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
