B

Step-by-step explanation:

n - 4 = 4.5 - 4 = 0.5

8(n - 4) = 8 *(0.5 ) = 4

6 *n = 6 * 4.5 = 27

8(n - 4) + 6n

8(0.5) + 6*4.5

4 + 27

31

Answer:

B.) 31

Step-by-step explanation:

Since the is [tex]8(n-4),[/tex] we substitute it with [tex]8x4.5-8x4.[/tex] [tex]8x4.5=36,[/tex] [tex]8x4=32.[/tex]

Now, it is [tex]36-32+6n[/tex].

[tex]6x4.5=27[/tex].

[tex]Now, 36-32+27.[/tex]
