Answer is D. I took the test.
Step-by-step explanation:
An expression is defined as a set of numbers, variables, and mathematical operations. The correct option is A, |2−(−7)|.
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
2x + 3 is an example of a variable mathematical expression. Every variable must have a coefficient, which is a number multiplied by the variable. The coefficient of x in the formula 2x + 3 is the number 2, and it signifies 2 times x plus 3.
The expression that shows the distance on the number line between 2 and −7 is |2−(−7)|. If we solve the given expression to calculate the distance then it can be solved as,
|2−(−7)|
= |2 + 7|
= |9|
= 9
Hence, The expression that shows the distance on the number line between 2 and −7 is 9 units.
