SECTION 1-7 : THE DISTRIBUTIVE PROPERTY

2. DISTRIBUTIVE PROPERTY : For any numbers, a, b, and c,
a( b + c) = a • b + a • c
TERM : a number, a variable, or the product of a number and a variable.
Examples :
CONSTANT : a term with no variable.
Examples :

3. COEFFICIENT : the number multiplying a variable.
Examples :
SIMILAR (LIKE) TERMS : terms with the same variables with the same exponents.
Examples :
SIMPLEST FORM : an expression written with no grouping symbols and no like terms.
Examples :

8. Use the distributive property to solve
mentally.
Deli sandwiches cost $4.95 each
including tax. Cody order five deli sandwiches. How much does he owe?
Solution : 5(4.95)
= 5(5 – 0.05)
= 5 • 5 – 5 • 0.05
= 25 – 0.25
= $24.75
