What is the coefficient of c ?

*
4c+7small2-r+2w

The coefficient of c in the given expression is 4.

To find the coefficient of c in the expression 4c + 7² - r + 2w, we look for the term that contains c.

The coefficient of c is the number that is multiplied by c. In this case, the coefficient of c is 4.

To find the coefficient of 'c' in the expression 4c + 7² - r + 2w, you need to look for the term that contains 'c' and determine the number that multiplies or precedes it.

In this case, the only term that contains 'c' is 4c. Therefore, the coefficient of 'c' is 4.
