A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.

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.

-6b + 7 < \( \frac{b}{5} \)
5 x (-6b + 7) < b
(5 x -6b) + (5 x 7) < b
-30b + 35 < b
-30b + 35 - b < 0
-30b - b < -35
-31b < -35
b < \( \frac{-35}{-31} \)
b < 1\(\frac{4}{31}\)

A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses:

(y - 5)(y - 8)
(y x y) + (y x -8) + (-5 x y) + (-5 x -8)
y² - 8y - 5y + 40
y² - 13y + 40

An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
