Answer 1

The answer is:

2

Work/explanation:

To evaluate this expression, I will begin by plugging in -6 for m.

First, plug in -6 for m :

`\sf{m^2+5m-4}`

Don't forget to plug it in everywhere you see x.

`\sf{(-6)^2+5(-6)-4}`

`\sf{36-30-4}`

Simplify:

`\sf{6-4=\boxed{\sf{6}}`

Therefore, the answer is 2.
