Answer:
1) a body of air with horizontally uniform temperature, humidity, and pressure.
2) the foremost part or surface of anything. the part or side of anything that faces forward: the front of a jacket.
3) A cold front is often associated with showers and thunderstorms. As it advances, often quite rapidly (50 to 65 km [30 to 40 miles] per hour), the cold air, which is relatively dense, undercuts the displaced warm air, forcing it to rise.
4) Cold Fronts. When a cold front passes through, the weather becomes significantly colder and drier. (It isn't uncommon for air temperatures to drop 10 degrees Fahrenheit or more within an hour of a cold frontal passage.) The weather map symbol for a cold front is a blue curved line with blue triangles.
5) When a cold front passes through, temperatures can drop more than 15 degrees within the first hour. Symbolically, a cold front is represented by a solid line with triangles along the front pointing towards the warmer air and in the direction of movement.

Answer:
x = 12
Step-by-step explanation:
The product of the length of the secant segment and its external part equals the square of the length of the tangent segment.
3*x = 6^2
3x = 36
Divide each side by 3
3x/3 = 36/3
x = 12

Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
