Question

4{m-n} if m= -7 and n=2

Answer 1

To evaluate the expression \(4(m - n)\) when \(m = -7\) and \(n = 2\), substitute the values of \(m\) and \(n\) into the expression and perform the calculations:

\[4(-7 - 2)\]

\[4(-9)\]

\[-36\]

So, when \(m = -7\) and \(n = 2\), the value of the expression \(4(m - n)\) is \(-36\).
