Answer:
C. 7x-5
Explanation:
Given the expression:
[tex]28x^2+29x-35[/tex]To determine the factor, we first factorize the expression.
[tex]\begin{gathered} 28x^2+29x-35 \\ =28x^2-20x+49x-35 \\ =4x(7x-5)+7(7x-5) \\ =(4x+7)(7x-5) \end{gathered}[/tex]Therefore, the expression that is a factor is 7x-5.
The correct choice is C.
