Answer :
To find an expression equivalent to
[tex]$$7f + 9f,$$[/tex]
we begin by noticing that both terms have the same variable [tex]$f$[/tex]. This means we can combine the coefficients of [tex]$f$[/tex].
1. Write the expression with the coefficients:
[tex]$$7f + 9f.$$[/tex]
2. Factor out the common variable [tex]$f$[/tex]:
[tex]$$f(7 + 9).$$[/tex]
3. Add the coefficients:
[tex]$$7 + 9 = 16.$$[/tex]
4. Multiply the common factor back:
[tex]$$f \cdot 16 = 16f.$$[/tex]
Thus,
[tex]$$7f + 9f = 16f.$$[/tex]
Among the provided options, the expression equivalent to [tex]$7f + 9f$[/tex] is:
[tex]$$\boxed{16f}.$$[/tex]
