Question

please solve fast I mark brainlist whose sum all are right​

Answer 1

Answer:

6) Let the zeros of cubic polynomial be

e,j,k

e+j+k=-b/a

here in this polynomial b=-8 and a=1

sum of zeros are -(-8)/1

8/1=8

7)cubic polynomial=ax3+bx2+cx+d

3x^3+5x^2+7x-11

8) above snapshot is your answer

9) Let new radius be r=r+20r/100=1.2r

area =4π(1.2r)/3

(1.7(4πr3/3)-4πr3/3)100/4πr3/3=72.8%

10)True

these are your answer. Mark ame brainlist
