Q. Which expression is equivalent to 3z+3z?Choices:(A) z+6(B) z6(C) 5z(D) 6z
Identify operation: Step 1: Identify the operation needed to simplify the expression 3z+3z. Since both terms are like terms (both have z), we add the coefficients (3 and 3) together. Calculation: 3+3=6. So, 3z+3z simplifies to 6z.
