x + y + z + x + 2z + 3y

2x + 4y + 3z


9xyz


4x + 2y + 3z


x2 + y4 + z3

Answer 1

Answer: A. 2x + 4y + 3z

Step-by-step explanation: Simplify by combining like terms that share the same variables.

Group like terms together:

(x + x) + (y + 3y) + (z + 2z)

Add the coefficients to combine like terms:

2x + 4y + 3z

Answer 2

Explanation:

Answer 1

x+x+y+3y+z+2z

2x+4y+3z

Answer 2

2x+4y+3z

( no like terms are there so it cannot be added)

Answer 3

9xyz

last two answers will also be similar as the question because unlike terms cannot be added..
