Which expression is equivalent to 6f+f?

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! :)
