Question

If k = -3 what is the value of k + (2k - 10) ?

A. –19
B. –7
C. 1
D. –14

Answer 1

A

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.
