Which of these are like terms in the following expression:

3x + 9x + 2x²

• 7, 24y

• 3x, 9x

• 3x, -9x

• 3x, -9x, 2x²

Simplify

-6k + 7k=

• k

• -k

• 12k

• -12k

Identify the like terms: 4k + 6t - 45k -2a + 23

• there are no like terms

• -2a and 6t

• 4k and -45k only

• 4k and -45k: 6t and 23

Identify the like terms: 8 - 5y - 8y + 12

• 12 and 5y

• -5y and -8y ONLY

• 8 and 12: -5y and -8y

• none

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

• 8a + 2b + 4

• 2a + 2b + 4

• 8ab

• 4ab + 4

 $Solve\ 21=3+4n+5n$  

• 9

•  $-7$  

• 6

• 2

Solve 5x - 4 + 2x = 3

• 1

• 2

• 3

• 4

Solve for x: 
7x + 5 + x - 3 + x = 5

• 1/3

• 3

• 3/7

• 1

 $21=3+\frac{4}{3}n+\frac{5}{2}n$  

• 18
  

•  $\frac{27}{6}$  

•  $\frac{19}{36}$  
  

•  $\frac{108}{23}$  

 $-118=-20-35x+7$  

•  $-5$
