17. 7 1⁄5 – 6 2⁄5 = ? a. 4⁄5 b. 13 3⁄5 c. 1 4⁄5 d. 1 1⁄5

The answer is 4/5, A. First, we should convert everything into an improper fraction. This gives us 36/5 - 32/5. Next, we have to subtract and get an answer of 4/5. Usually, we would have to convert this number back into a mixed number, but 4/5 is less than 1 and is therefore the answer.

Hope this helps!

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 *_*
