Answer 1

Answer:

$C. -7x^2-28x$

Step-by-step explanation:

The given expression is $4x(3x-7)-19x^2$

We apply the distributive property to expand the parenthesis

$12x^2-28x-19x^2$

Regroup similar terms to get:

$12x^2-19x^2-28x$

Combine the similar terms to obtain:

$-7x^2-28x$

The correct option is C.
