Carmen simplifies the expression (4 y + 8 x + 6) + 25 + (4 x + 6 y + 7). The coefficient of the variable y in her simplified answer is 4. 6. 10. 12.

10

Step-by-step explanation:

original expression:

4y + 8x + 6) + 25 + (4x+6y+7)

Let's simplify it step-by-step:

4y+8x+6+25+4x+6y+7x (removing the parentheses)

4y+12x + 6+25+6y+7 (adding together similar terms in x)

10y+12x+6+25+7 (adding together similar terms in y)

10y+12x+38 (adding together similar terms with no variable)

So, from the final expression, we see that the coefficient for y is 10.
