X= 17/29

sorry if i am wrong, hope this helped!

The answer is 41.7 because 1.39 times 30 is 41.7

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 *_*
