What is an Expression?
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
For the given expression 4x + 9 - y(6x + 7), the following things are can be written,
- 4 and 6 are coefficients.
- 9 and 7 are constants.
- x and y are variables.
Thus, the statements that are true are:
- The 6 in the third term is a coefficient.
- The 9 in the second term is a constant.
- The y in the third term is a factor.
Hence, the statements that are true are 1, 3, and 5.
