Simplify the expression 7x^2+8x−2(x^2+4)−6 . What is the coefficient of x in the simplified expression?(1 point)
The simplified expression is 7x^2+8x−2(x^2+4)−6 = 7x^2 + 8x - 2x^2 - 8 - 6 = (7x^2 - 2x^2) + 8x - (8 + 6) = 5x^2 + 8x - 14.
The coefficient of x in the simplified expression is 8. Answer: \boxed{8}.
