Answer:

The expression are not equivalent.

Step-by-step explanation:

For Angeline we have the next process:

[tex](7+15)\times(38+15)=22\times53=1166[/tex]

For MeiLing we have:

[tex]15\times(7+38)=15\times45=675[/tex]

Then we have that the students expressions are not equivalent.

The process to solver the expressions was solving first the parenthesis and after that solver the multiplication.
