The width of a rectangle is (x + 2).
if its area is x4 + 2x3 + 6, find its length.

The length of rectangle is given as

Solution:

Given that,

Width of rectangle = x + 2

Area of rectangle =

Length of rectangle = ?

The area of rectangle is given as:

Therefore, length is given as:

Substituting the given values we get,

There are no common factors that could be cancelled. Also numerator cannot be factored further

Thus length of rectangle is given as

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.

the answer is 62.8 cubic units
