Answer
C. 19
Explanation
The absolute value of any digit is the magnitude or its size. The negative side is not considered.
It can also be defined as the actual magnitude of a numerical value or measurement, irrespective of its relation to other values.
It is represented as; /x/.
4|B| – |D|
|B| = |-7| = 7
|D| = |9| = 9
∴ 4|B| – |D| = (4 × 7) - 9
= 28 - 9
= 19
