The area of a trapezoid is found using the formula a=1/2h(b^1+b^2), where b^1 and b^2 are the parallel sides of the trapezoid and h is the height. the area of a trapezoid is 18km^2 , with bases 5 km and 7 km. what is the height, in kilometers?i need this sooon

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 *_*
