Melanie · Answer

Answer:   Here is your answer .   Step-by-step explanation:    a.  : 5( -2 ) - 2     - 10 - 2     =  - 12        b.  : 5 {n}^{2}  + 5n  :  - 2    5 {( - 2)}^{2}  + 5( - 2) - 2     = 5(4) - 10 - 2     = 20 - 12     = 8          c.  :  {n}^{3}  + 5 {n}^{2}  + 5n - 2      { (- 2)}^{3}  + 5 { (- 2)}^{2}  + 5( - 2) - 2    8 + 5(4)  - 10 - 2     = 8 + 20 - 12     = 28  - 12     = 16   Hope it will help you.

Answer:   5(-2)-2=-10-2=-12  5(-2)^2+5(-2)-2=5(4)-10-2=20-12=8  (-2)^3+5(-2)^2+5(-2)-2=-8+5(4)-10-2=-8+20-12=-12-12=-24
