2) \( 1+\frac{a}{4}+7 a \) Terms: Coefficients: Variables: Constants:

The expression \( 1+\frac{a}{4}+7 a \) features a constant term of 1, which stands alone without any variable attached. The coefficient in the term \(\frac{a}{4}\) is \(\frac{1}{4}\), while for the term \(7a\), the coefficient is 7. The variable present in this expression is 'a', which is treated as a placeholder for any number you wish to substitute. To break it down further, remember that simplifying this expression can often help in understanding its dynamics better. You can combine like terms when possible. In this case, you might want to rewrite the expression to have a uniform appearance, making it clearer how 'a' influences the overall value by combining terms under a single denominator if you feel inclined. It's a wonderful exercise in algebra that can help sharpen your skills!
