Question

fill in the parts - whole model for the following equation.
$5x + 2x = (\underline{quadquad})$
\

$$\begin{tabular}{|c|c|} \\hline \\multicolumn{2}{|c|}{\ ule{0.5cm}{0.15cm}|\ ule{0.5cm}{0.15cm}} \\\\ \\hline $5x$ & $2x$ \\\\ \\hline \\end{tabular}$$

answer attempt 1 out of 9

Explanation:

Step1: Identify like terms

The terms \(5x\) and \(2x\) are like terms (same variable \(x\) with exponent 1).

Step2: Combine like terms

To combine \(5x + 2x\), we add the coefficients (5 and 2) and keep the variable \(x\). So \(5 + 2 = 7\), and the result is \(7x\).

Answer:

\(7x\)
