Answer:

A

Step-by-step explanation:

We have the expression [tex]k+(2k-10)[/tex]

We want to find the value when k is -3. So, substitute -3 for k and evaluate:

[tex]\Rightarrow (-3)+(2(-3)-10)[/tex]

Multiply:

[tex]=-3+(-6-10)[/tex]

Subtract:

[tex]=-3+(-16)[/tex]

Add:

[tex]=-19[/tex]

Therefore, our answer is A.
