Answer:

27

Step-by-step explanation:

To solve this problem, let us follow it step by step;

Let Peter's number  = P;

    So;

   ⇒   P - 17

   ⇒  -2 (P - 17 )

   ⇒  -2 (P - 17 ) = -20

Solve the problem for P;

       -2 (P - 17 ) = -20

       -2P + 34  = -20

       -2P = -20 -34

         -2P  = -54

             P = 27

Answer:

\boxed{  \bold{\sf{ { \boxed{ \sf{8 {x}^{5}  + 4 {x}^{4}  - 12 {x}^{2} }}}}}}

Option C is the correct option.

Step-by-step explanation:

\sf{4 {x}^{2} (2 {x}^{3}  +  {x}^{2}  - 3})

Distribute 4x through the parentheses.

\dashrightarrow{ \sf{4 {x}^{2}   \times \: 2 {x}^{3}  + 4 {x}^{2}   \times  {x}^{2}    - 4 {x}^{2}   \times 3}}

\dashrightarrow{ \sf{8 {x}^{5}  + 4 {x}^{4}  - 12 {x}^{2} }}

Hope I helped!

Best regards! :D
