Add Linear ExpressionsSection 5.6
VocabularyLinear Expression- an _______ expression in which the variable is raised to the first power.
Add Linear ExpressionsThe table below gives some example of expressions that are linear and some examples of expressions that are not linear.
You can add linear expression with or without models. Sometimes you will need to use zero pairs.
Examples• 1. (3x - 5) + (2x - 3)
• 2. (2x - 4) + (3x - 7)
Examples• 3. 6(x + 7) + (x + 3)
• 4. (12x + 19) + 2(x - 10)
Word Problems• 5. A rectangle has side lengths (x+4)
feet and (2x-2) feet. Write a linear expression in simplest form to represent the perimeter. Find the perimeter if the value of x is 7 feet.
Word Problems • 6. Write a linear expression in simplest
form to represent the perimeter of the pentagon. Then find the perimeter if the value of x is 3 yards.
(3x) yd (3x) yd
(2x) yd(2x) yd
(x + 4) yd
Essential Question• Explain how adding linear expressions is
