Question

complete the expressions and select the missing property.
write each answer as a number, a variable, or the product of a number and a variable.
$5y\cdot4$
$=\square\cdot5y$
$=\square$ multiply

Explanation:

Step1: Apply Commutative Property of Multiplication

The commutative property of multiplication states that \(a \cdot b = b \cdot a\). So for \(5y \cdot 4\), we can rewrite it as \(4 \cdot 5y\).

Step2: Multiply the Coefficients

Now, multiply \(4\) and \(5y\). \(4 \cdot 5y=(4\times5)y = 20y\).

Answer:

First box: \(4\) (property: Commutative Property of Multiplication)
Second box: \(20y\)
