Simplify the expression
y+2y+3z
A. 2y+3z
B. 3y+3z
C. 2y^2+3z
D. 6yz
Is the answer B?
Yes. You are right.
To simplify the expression y + 2y + 3z, you can combine the like terms. Like terms have the same variable(s) raised to the same exponent(s).
In this case, y and 2y are like terms because they both have the variable y raised to the first power.
So, you can add y and 2y to get 3y.
Now, the expression becomes 3y + 3z.
Therefore, the simplified expression is 3y + 3z, which corresponds to option B.
So, yes, the answer is B.
