Aroom is 12 feet long and 10.5 feet wide. a scale model of the room is 3.5 feet wide. what is the area of the scale model?

Scale of the model = 3.5 / 10.5 = 1/3
so the length of the model = 1/3  * 12 = 5 feet

Area of the scale model = 4 * 3.5 = 14 sq ft

If 3.5 is one third of 10.5 than one third of 12 must be four. 3.5 times 4 is
14

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 *_*
