It is defined as the combination of constants and variables with mathematical operators.
It is given that:
The expression in word form:
"9 less than the product of 5 and a number n"
Here n is the number.
The product of 5 and the number n is 5n
9 less than the product of 5 and a number n:
= 5n - 9
If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.
The above expression represents the "9 less than the product of 5 and a number n"
Thus, the expression 5n - 9 represents the 9 less than the product of 5, and a number n option (D) 5n -9 is correct.
