The rectangular plant box has an area of 9b² - 64 square cm, it is 3b - 8 cm wide. How long is the rectangular lot?
[tex]\:[/tex]
Solution:
[tex]\tt \Large \rightarrow \frac{9b^2 - 64}{3b - 8}[/tex]
[tex]\tt \Large \rightarrow \frac{(3b - 8) \times (3b + 8)}{3b - 8}[/tex]
[tex]\tt \Large \rightarrow \frac{\cancel{(3b - 8)} \times (3b + 8)}{\cancel{3b - 8}}[/tex]
[tex]\tt \Large \rightarrow \purple{\bold{3b + 8}}[/tex]

Answer:
The rectangular lot is [tex]\tt \Large \purple{\bold{3b + 8 \: \: cm}}[/tex] long.
