The table shows the width and length of different pictures that Coby has enlarged for the school yearbook: Enlarged Pictures Wid
Savatey [412]

Answer:

42 inches

Step-by-step explanation:

Im guessing that the the table looks like this:

Width     Length

3           7

6           14

9           21

So we can see the numbers on the right are increasing by 3 and the numbers on the left are increasing by 7.

The width is 3 times some number, and the length is 7 times the same number.

So if the width was 18 then we know the number would be 3 because 3 * 6 = 18

If that number is 6, then the length will be 6 * 7 = 42

So the length is 42 inches
