Question

• $3(z + 1) + 3(z + 1)$
• $6(z + 1)$

yes no

Explanation:

Step1: Combine like terms

We have \(3(z + 1)+3(z + 1)\). Since both terms are \(3(z + 1)\), we can think of this as \(3(z + 1)+3(z + 1)=(3 + 3)(z + 1)\).

Step2: Simplify the coefficient

Simplify \(3+3\) which equals \(6\). So, \((3 + 3)(z + 1)=6(z + 1)\).

Answer:

Yes
