The answer would have to be 3+2x
The line four times the sum of 3.2 and a number is the number less 1.4 can be expressed as 4(n+3.2) = n-1.4.
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given to us
Four times the sum of 3.2 and a number is the number less than 1.4
Let the number be n.
It is given that the sum of 3.2 and number,
n + 3.2
Four times the sum, therefore,
4(n+3.2)
The total we got is the number less 1. 4. thus,
4(n+3.2) = n - 1.4
Hence, the line four times the sum of 3.2 and a number is the number less 1.4 can be expressed as 4(n+3.2) = n-1.4.
