Which expression replaces the box to form an equation?

Answer:
Option B is correct
[tex]5(8) \div 5+ 3(8)[/tex]
Step-by-step explanation:
Given the equation: [tex]40 \div 5+3 \cdot 8[/tex]
we can write
40 as [tex]5 \cdot (8) = 5(8)[/tex]
[tex]3 \cdot 8 = 3 (8)[/tex]
then;
our equation becomes:
[tex]5(8) \div 5+ 3(8)[/tex]
therefore, the expression which replace the box to form an equation is [tex]5(8) \div 5+ 3(8)[/tex]
