Lesson 1.4 WarmUp:
1) Evaluate: 14 2 6 ­ 52
2) Find the perimeter & area of a square with
sides that measure 4.5 inches.
3) What is the reciprocal of 4?
5
4) What is the area of a circle with a diameter of 1 inch?
5) Evaluate the expression, when c = ­6

Lesson 1.4:
*Distributive Property ­­> a(b + c) = ab + ac
a(b ­ c) = ab ­ ac
ex­­> 3(2 + 5) =
ex­­>4(9 ­ 7) =
*like terms ­ terms that contain the same variables, with corresponding variables
having the same power
5x2 + 2x ­ 4 6a2 + a2 + 2a
3 terms like terms unlike terms

4. Lesson 1­4.notebook August 20, 2013
*The coefficient of a term is the numerical factor.
ex­­> 6ab x2 y
3
coefficient is:
*An expression is in "simplest form" when it contains
no like terms or parentheses.
