Answer:

-2265

Step-by-step explanation:

First, we replace x with 20.

[tex]f(20)=-5*20^2-13*20-5[/tex]

Then, we evaluate.

The * stands for multiplication.

[tex]f(20)=-5*20^2-13*20-5\\-5*400-260-5\\-2000-260-5\\-2265[/tex]

[tex]f(20) = - 5 \times {20}^{2} - 13 \times 20 - 5 \\ [/tex]

[tex]f(20) = - 5 \times 400 - 260 - 5[/tex]

[tex]f(20) = - 2000 - 260 - 5[/tex]

[tex]f(20) = - 2265[/tex]
