Which statement best reflects the solution(s) of the equation? 1x−1+2x=xx−1 There is only one solution: x = 2. The solution x = 1 is an extraneous solution. There is only one solution: x = 2. The solution x = 0 is an extraneous solution. There is only one solution: x = 1. The solution x = 2 is an extraneous solution. There are two solutions: x = 1 and x = 2.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

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

where are the graphs?

step-by-step explanation:

any of them that add up to 180 degrees.
