Question

Which expression is equivalent to 6f+f?

Answer 1

`f + 5f + f` is equivalent to
`6f + f`.

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.

`6f + f\\6(2) + 2\\12 + 2 = 14`

`f + 5f + f\\2 + 5(2) + 2\\2+10+2 = 14`

Hope this helps! :)

Answer 2

A

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
