Adding Linear Expressions

Adding Linear Expressions

Lesson 5-2

By the end of this lesson I will be able to add linear expressions by combining like terms and using the distributive property

Lesson 5-2

Linear Expressions

• Variable is raised to the first power

• Variable cannot be in the denominator

• Variables cannot be multiplied

Multiple Select

Select all the answers that represent linear expressions

• 2x² + 1

• 2x + 2

• x - 15

• 1/2x³ + 5

Multiple Select

Select the graphs that represent linear expressions:

Adding Linear Expressions

• Get rid of the parentheses

• Combine like terms

• We can do this because the plus sign in between the sums when distributed keeps all the signs the same

Multiple Choice

Simplify by adding these linear expressions: (9x + 7) + (x + 3)

• 10x + 10

• -10x - 10

Multiple Choice

Add the linear expressions:

(3x + 7) + (10x -3)

• 13x + 10

• 13x + 4

Multiple Choice

Simplify: (6p + 4) + (-5p + 8)

• -30p + 48

• p + 12

Multiple Choice

Simplify: (5x - 1) + (3x + 6)

• -15x + 10

• 8x + 5
