the answer is 7+5x because when you inverse something you reverse it.
1-(b)
2-(b)111600
3-(a)
4-(d)
The names PNM and MPN are perfectly valid. The order of the letters doesn't matter. In fact, there are 6 ways to name this plane if we just use the 3 letters. If we include "plane Z", then there are 7 total ways to name the plane.
For some reason, your teacher wants P to be the third letter as s/he mentioned MNP and NMP. But again, the order doesn't matter.
Multiply (-5) and (7) together to get -35
Then multiply (6) and (-2) together to get -12
Finally multiply -35 and -12 together to get 420
So your answer to this is 420
Hope this helped :)
Have a good day
