Kelly ran 2 miles and burned 240 calories. the next day she ran 3 miles and burned 360 calories. the next day4 miles and 480 miles. if this pattern continues, how many calories will she burn if she runs 8 miles?

Kelly burns 120 calories per every mile she runs ( 240/2 = 120, 360/3 = 120, etc.).

120 calories x 8 miles = 960 calories

Kelly will burn 960 calories if she runs 8 miles.

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 *_*
