Me with the question for the surface area of a cylinder

Formula is 2r^2+2rh

2 x 3.14 x 4 x 4 = 100.48

2 x 3.14 x 4 x 5 = 125.6

Total: 226.08, aka answer choice D

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 *_*
