A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).

To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the > sign and the answer on the other.

3b - 6 > 6 - 7b
3b > 6 - 7b + 6
3b + 7b > 6 + 6
10b > 12
b > \( \frac{12}{10} \)
b > 1\(\frac{1}{5}\)

To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.

A triangle is a three-sided polygon. It has three interior angles that add up to 180° (a + b + c = 180°). An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite (d = b + c). The perimeter of a triangle is equal to the sum of the lengths of its three sides, the height of a triangle is equal to the length from the base to the opposite vertex (angle) and the area equals one-half triangle base x height: a = ½ base x height.

To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the > sign and the answer on the other.

-x - 5 > \( \frac{x}{1} \)
1 x (-x - 5) > x
(1 x -x) + (1 x -5) > x
-x - 5 > x
-x - 5 - x > 0
-x - x > 5
-2x > 5
x > \( \frac{5}{-2} \)
x > -2\(\frac{1}{2}\)
