Final answer:
To find the value of the expression 6q + 9q + 4 - 5q, combine like terms to get 10q + 4. This expression can be evaluated if a specific value of q is known. The sign of the result depends on whether q is positive or negative.
Step-by-step explanation:
To calculate the value of 6q + 9q + 4 - 5q, we begin by combining like terms. The terms that include the variable q are 6q, 9q, and -5q. When we combine these, we get (6q + 9q - 5q) which simplifies to 10q. Then we add the constant term which is 4, so our final simplified expression is 10q + 4.
If we are only simplifying the expression and not solving for a specific value of q, this is as far as we can go. However, if the value of q is given, we can substitute it into the simplified expression to find a numerical answer. The arithmetic sign of the final answer will depend on the value of q; if q is positive, the entire expression will be positive, and if q is negative, the expression could be negative or positive depending on the magnitude of q relative to the constant.
