Question

What is 4| m - n | if m = -7 and n = 2
a. 26
b. 18
c. 10
d. 28

Answer 1

After evaluating the expression 4|m - n| with m = -7 and n = 2, the result is 36, indicating that none of the options provided are correct.

Step-by-step explanation:

To calculate 4|m - n| with given values of m = -7 and n = 2, you first need to determine the absolute value of m - n. This is achieved by subtracting n from m:

• m - n = -7 - 2 = -9

Next, find the absolute value of the result, which removes any negative sign:

• |m - n| = |-9| = 9

Finally, multiply the absolute value by 4:

• 4|m - n| = 4 × 9 = 36

Therefore, the answer is 36, which means none of the provided options a. 26, b. 18, c. 10, or d. 28 are correct
