Question

Select the expressions that are equivalent to 7(7f)1. 49f2. 7(f+6f)3. f+144. f+49

Answer 1

49f and 7(f + 6f)

EXPLANATION :

From the problem, we have :

`7(7f)`

When multiplied, it will be 49f

When breaking it down, 7f is equal to f + 6f. Then it will be 7(f + 6f)

The next options f + 14 and f + 49 has two terms, so it will not be equivalent to the given expression with one term.

So the only expressions that are equivalent to the given expression are 1 and 2
