In set builder notation how do you write the solutions of the inequality 5x +17 is greater than or equal to seven why do you put in for now i didn’t say for

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
