A four - digit serial number is to be created from digits 0 through 9. How many of these serial number can be created if 0 can not be the first digit, no digit may be repeated, and the last digit must be 5?

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

3-4
