Width = w
Length = w + 1
Area = 30
w(w+1) = 30
w² + w = 30
w² + w - 30 = 0
w² + 6w - 5w - 30 = 0
w(w + 6) -5(w + 6) = 0
(w + 6)(w - 5) = 0
w = 5 or -6
Since the width cannot be negative, the width is 5 units.
Hence, the width is 5 units and the length is 6 units.

He has 10 spice jars, but the spice rack only holds 8 spice jars.
Calculate in how many ways he can choose 8 spice jars from 10 spice jars using combination:

Each combination of 8 spice jars that he chooses he can arrange in 8! ways.
He can choose 8 spice jars in (10!)/(8!×2!) ways and arrange each combination in 8! ways.
Using the rule of product:

He can arrange 8 jars on the spice rack in c. 1,814,400 ways.
well half 40 is 20 and 1 third of 60 is 20 and 1 fourth of 80 is 20 and i 1 fifth of 100 is 20 so that is who they are related
