# APPLICATIONS OF LINEAR EQUATIONS

Key Words:

• Subtraction - difference, minus, decreased by, subtracted from

• Multiplication - product, times, double (2x), tripled (3x)

• Division - quotient, ratio, divided by

Formulas:

• Area of square:

• Area of a rectangle:

• Area of a triangle:

• Area of a trapezoid:

• Area of a circle:

• Perimeter:

In other words, add each side together.

• Circumference of a circle:

Angle Properties:

• Vertical Angles are opposite angles formed by intersecting lines. Vertical angles always have the
same measurement.

• Complementary Angles are two angles whose sum is 90°.

• Supplementary Angles are two angles whose sum is 180°.

Common Mistakes to Avoid:

• For perimeter, be sure to add EACH AND EVERY side in the formula.

• Be very careful to translate the problem into correct mathematical form. When it has been translated,
you should be able to read it back.

• Be careful: a minus b is translated a - b; whereas, a less than b is translated b - a.

• Be careful on the difference between these two statements:

- The sum of four times a number and 5 is translated 4x + 5.

- Four times the sum of a number and 5 is translated 4(x + 5).
