Explanation:

Given expression,

$\\ {\longrightarrow \qquad{ \sf{6(x + 7) + 3x}}}\\ \\$

Using distributive property we get,

$\\ {\longrightarrow \qquad{ \sf{6x + 42 + 3x}}}\\ \\$

Adding like terms (6x and 3x) we get,

$\\ {\longrightarrow \qquad{ \sf{9x + 42 }}}\\ \\$

So, From the given options, Option C is equivalent to 6(x + 7) + 3x .
