$34x^2+11x$

#### Work Step by Step

Using $a(b+c)=ab+ac$ or the Distributive Property and then combining like terms, the given expression, $6x^2-x+4(7x^2+3x)$, simplifies to \begin{array}{l}\require{cancel} 6x^2-x+4(7x^2)+4(3x) \\\\= 6x^2-x+28x^2+12x \\\\= (6x^2+28x^2)+(-x+12x) \\\\= 34x^2+11x .\end{array}
