The table shows the width and length of different pictures that katie has enlarged for the school yearbook: enlarged pictures width (inch) length (inch 5 6 10 12 15 18 based on the table, what is the length of a picture that has a width of 20 inches? 24 inches 35 inches 38 inches 40 inches

24 inches is i am not mistaking

6 to 12 is +6

12 to 18 is +6

so 18 to 24 is +6

To do the scientific notation you would:
Multiply the coefficients and then round the number of significant figures into the coefficient with the smaller number.
Then you would add your exponents
And then your result is converted into the scientific notation.

Hope this helps! :3
