Find the length of a picture frame who’s width is 3 inches and whose proportions are the same 9 inch wide by 15 inch long

5 inch

Step-by-step explanation:

The frames are proportional, so we can set the ratios equal:

width / height = width / height

3 / h = 9 / 15

9h = 45

h = 5

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
