The area of the rectangle to the right is 68. Find the value of X. Length is x+4 and the width is x-9​

Cathy's number is not divide by 7 and 9

Step-by-step explanation:

Anh’s number is divisible by all numbers from 1 to 10 except 7.  

Hence, Anh’s number is 8*9*10 = 720

Bill’s number  does not divide by 9, hence his number would be = 3*8*5*7 = 840

The sum of numbers of all three is divisible by all numbers between 1 to10  

So the sum number is = 10*9*8*7 = 5040

Number of Cathy = 2520  – 720 -840 = 960

960 is not divisible by 7 and 9
