Answer:

A

Step-by-step explanation:

This is because 6f+f is just 7f.

f f f f f f+f = fffffff

Soooo, ONLY A gives us 7f when added together again.

f+5f+f=7f.

f+ f f f f f +f = fffffff

Answer:

[tex]f + 5f + f[/tex] is equivalent to [tex]6f + f[/tex].

Step-by-step explanation:

You can plug in any numbers to both expressions and they will always have the same outcome.

For example, let's plug in 2.

[tex]6f + f\\6(2) + 2\\12 + 2 = 14[/tex]

[tex]f + 5f + f\\2 + 5(2) + 2\\2+10+2 = 14[/tex]

Hope this helps! :)
