Answer:
An equivalent expression to show the relationship of multiplication and addition of j+j+j+j+j is 5j
Explanations:
The relationship between multiplication and addition is that multiplication occurs when one number is repeatedly added.
From the given question, you can see that "j" is repeatedly added together to have:
j + j + j + j + j
Since "j" is added in 5 places, hence;
j + j + j + j + j = 5j
This means that if we multiply 5 and j, it shows we are adding "j" five times.
