Respuesta :

Answer:

Option B

Step-by-step explanation:

Given expression in the picture is,

[tex]13a^2-\frac{1}{4}(8a^2-12)+5a[/tex]

[tex]=13a^2-\frac{1}{4}(8a^2)+\frac{12}{4}+5a[/tex] [Distributive law]

[tex]=13a^2-2a^2+3+5a[/tex]

[tex]=11a^2+5a+3[/tex]

Therefore, Option B will be the correct option.
