Twice a number divid by 6 is 42

A number=x

2x/6=42
2x=252 by multiplying both sides by 6
x=126 by dividing both sides by 2 to isolate the variable

Let’s call this number ‘n’.

Twice a number is 2n.

2n / 6 = 42

2n = 252

n = 126.

I’m confused as to what you are asking 66 2/3 percentage wise

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
