Jane had a rectangular frame 30 inches in length and 24 inches in width. stan made a similar frame that is smaller in size. which of the following could be the dimensions of the frame stan made? a length = 20 inches, width = 25 inches b length = 15 inches, width = 8 inches c length = 24 inches, width = 18 inches d length = 15 inches, width = 12 inches an explanation on why the correct answer is correct would be much appreciated.

the least common denominator is 40

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

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
