If k = -3 what is the value of k + (2k - 10) ?<br><br> A. –19<br> B. –7 <br> C. 1<br> D. –14
gladu [14]

Answer:

A

Step-by-step explanation:

We have the expression k+(2k-10)

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

\Rightarrow (-3)+(2(-3)-10)

Multiply:

=-3+(-6-10)

Subtract:

=-3+(-16)

Add:

=-19

Therefore, our answer is A.
