Step-by-step explanation:
just multiply the 2 together to get the area
it would just be
[tex](5x) \times (2{x}^{2} - 4x + 13)[/tex]
use the distributive property
[tex]10 {x}^{3} - 20 {x}^{2} + 65[/tex]
unless you want to simplify the answer, this would be the answer
simplified, it would be
[tex]5(2{x}^{3} - 4 {x}^{2} + 13)[/tex]
