Answer:

6

Explanations:

The given absolute value expression is:

| 2x+ z | + 2y

Substitute x = 2.1, y = 3, z = -4.2 into the given expression:

[tex]|2(2.1)+(-4.2)|+2(3)[/tex]

This can be simplifed as:

[tex]|2(2.1)-4.2|+6[/tex][tex]|4.2-4.2|+6[/tex]

Since |4.2-4.2| = 0, the expression above becomes:

0 + 6

= 6

Therefore, the absolute value of the expression, after simplification, is 6
