Simplify Expressions with and without Variables

Simplify by combining like terms:
5a + 2b - 3a + 4

• 8a + 2b + 4

• 2a + 2b + 4

• 8ab

• 4ab + 4

Combine like terms to simplify: a + 2a + 7

• 9a

• 3a + 7

• 2a + 7

• 9

Combine like terms to simplify: 8x - 8d

• 8

• xd

• 0

• They are unlike terms, so cannot be simplified.

Which expression is equivalent to
v + v + v + v + v?

• 5v

• v⁵

• v + 5

• v5

Simplify the following expression:
-10x + 15 - 3x + 2

• 13x² + 17

8(x + 5)

• 8x + 13

• 8x + 5

• 8x + 40

• 13x

Use the distributive property to write an equivalent expression.

• 3x + 12

• x + 7

Simplify:  3 (a +b + c)

• a+b+c

• 3+3+3

• 3a + 3b +3c

• a-b-c

Distribute the following:
10(z - 6)
