To find the value of the expression [tex]\( 8 - |2g - 5| \)[/tex] when [tex]\( g = -3.5 \)[/tex], follow these steps:

1. Substitute [tex]\( g = -3.5 \)[/tex] into the expression [tex]\( 2g - 5 \)[/tex]:
[tex]\[ 2(-3.5) - 5 \][/tex]

2. Calculate the multiplication and subtraction:
[tex]\[ 2 \times -3.5 = -7 \][/tex]
[tex]\[ -7 - 5 = -12 \][/tex]

3. Find the absolute value of the result from step 2:
[tex]\[ |-12| = 12 \][/tex]

4. Substitute the absolute value back into the original expression:
[tex]\[ 8 - 12 \][/tex]

5. Calculate the final result:
[tex]\[ 8 - 12 = -4 \][/tex]

So, the value of the expression [tex]\( 8 - |2g - 5| \)[/tex] when [tex]\( g = -3.5 \)[/tex] is [tex]\(-4\)[/tex].

The correct answer is:
D. -4
