What is the correct order of operations for simplifying the expression 2 – 3x + 5 + 7(y – 5x)2 + x?
square the binomial, combine like terms, and then distribute 7 inside the parentheses
O combine like terms, square the b omial, and then distribute 7 inside the parentheses
distribute 7 inside the parenthese square the binomily, and then combine like terms
O square the binomial, distribute 7 il side the parentheses, and then combine like terms

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.

omg what happend to your question? if you could edit this question i can

step-by-step explanation:

i hope this is what you were looking for.

see attached graph

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
