Answer: The correct answer is there are no common variables among all three terms and the resulting expression when factoring out the GCF is 7(4vw + 7v + 5w).
Explanation:
We are given a polynomial (28vw + 49v + 35w) which has three terms: 28vw, 49v and 35w.
This polynomial can be simplified by taking 7 out of the equation, because it is common to all the three terms.
The simplified equation becomes: 7(4vw + 7v + 5w)
The greatest common factor is the constant which is common to all the terms of the polynomial and for this equation, the GCF is 7.
