Find the sum of the following situation:

a hang glider descended 33.57 feet, and then ascended 14.98 feet.

The answer would be 18.59 feet.  33.57 - 14.98 = 18.59 It descended first the ascended so it went down then back up. So you would subtract.

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 *_*
