The area of a rectangle is pool is (15x-9) square units. factor 15x-9 to find possible dimensions of the pool

3 and (5x-3).

Step-by-step explanation:

The area of a rectangle is

It is given that the area of a rectangle is pool is (15x-9) square units.

We need to find the factors of (15x-9), to find the dimensions of the pool.

It can be rewritten as

It is clear that 3 is GCF.

Taking out GCF, we get

Since the area of a rectangle is the product of its dimensions, therefore 3 and (5x-3) are dimensions of the pool.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

answer: idk
