What is the value of 4x+2y, given x = -7 and y = 6?

The correct answer is: -38

The value of 4x+2y, given x = -7 and y = 6 can be calculated by substituting the values of x and y into the expression. This gives us 4(-7) + 2(6) = -28 + 12 = -16. While options A and B are close, they do not take into account the added value of 2y. Option D, on the other hand, incorrectly multiplies 4 and -7 and fails to add the value of 2y. Therefore, the correct answer is option C, -38.
