Name the property of arithmetic used to rewrite the numeric statement. (6+3)+21-8=6+(3+21)-8(6+3)+21−8=6+( 3+21)−8

It is 198,87032,750 + 375 = 33145 so, we take the 6% and we make it a decimal (0.6) and multiply that, then that is your answer

2160ft^3 i think you could use a formala to you out with this in the future

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 *_*
