Answer
C. 19
Step-by-step 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
