a) ±3 b) ±18

Step-by-step explanation:

a) x^2+1/x^2=7

Add 2 both sides to complete the squares

x^2+1/x^2+2=7+2

(x+1/x)^2=9

(x+1/x)=±3

b) (x+1/x)=±3

Cubing both sides, we have

x^3+1/x^3+3(x*1/x)*(x+1/x)=±27

x^3+1/x^3+3*±3=±27

x^3+1/x^3=±18

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
