Question

B.3 Evaluate variable expressions involving integersAZTIf h = –3 and j = –5, what is j − 3h?

Answer 1

- The solution steps are given below:

`\begin{gathered} h=-3,j=-5 \\ \text{ Substitute the values of j and h into the expression given. We have:} \\ √(j-3h)=√(-5-3(-3)) \\ \\ =√(-5+9)=√(4) \\ √(4)=2 \\ \\ \therefore√(j-3h)=2 \\ \end{gathered}`

Final Answer

The answer is 2
