Answer: The sign is positive.
Step-by-step explanation:
a > 0 and b < 0
So, a·b < 0
⇒ -4·a·b > 0
⇒ -4·a·b - 4·a·b > 0
Hence, the sign will be positive

Lines f and g are parallel and the two angles are same-side angles, so they add up to 180 degrees. An equation for this would add up to 180, then solve for x to find the answer to the problem.
5x + (9x + 26) = 180, combine the like terms.
14x + 26 = 180, subtract 26 from both sides.
14x = 154, divide both sides by 14.
x = 11; so your answer is B. 11.
