Answer:
Option C.
Step-by-step explanation:
The given expression is
[tex]30-6v-18w[/tex]
We need to find the expression which is equivalent to the given expression.
The given expression can be rewritten as
[tex]6\times 5-6\times v-6\times 3w[/tex]
The greatest common factor (G.C.F.) is 6. Taking out G.C.F., we get
[tex]30-6v-18w=6(5-v-3w)[/tex]
Hence, the correct option is C.
