Question

What is the coefficient of the c-term of the algebraic expression

Answer 1

A coefficient is the number attached to a term. In this case we want to know the number attached to the term c

14a  - 72r - c - 34d

If there is no number visible in front of a coefficient then you can assume that there is an invisible 1 in front of it.

14a  - 72r - 1c - 34d

This case the coefficient of the c-term is:

-1

The reason it is negative and not just positive 1 is because the subtraction sign acts as a negative sign

Hope this helped!
