2+7z+15=

Calculate Tape Rolls: First, we need to determine how many rolls of tape the electrician needs by dividing the total amount of tape required by the amount of tape on each roll. $\newline$ Calculation: $8,000 \, \text{cm}$ (total tape needed) $\div 2,000 \, \text{cm}$ (tape per roll) $= 4$ rolls
Combine Like Terms: Now, let's address the new math problem by combining the like terms in the expression $2 + 7z + 15$ . First, identify the like terms. In this expression, the like terms are the constant numbers $2$ and $15$ .
Combine Constants: Combine the constants $2$ and $15$ to get a new constant. $\newline$ Calculation: $2 + 15 = 17$
Write Equivalent Expression: Now, write the equivalent expression by combining the new constant with the variable term. $\newline$ Equivalent expression: $17 + 7z$
