Answer:
There is no plug-in for x.
X=0.
(0+4) - (0-1) = [(4 - (-1)] = 5.
To simplify combine like terms:
8m + 7m = 15m
4n - 2n = 2n
Simplified: 15m + 2n
The -9 stays the same the whole time but the other number being multiplied decreases by one each layer, so the next three would be:
-9 x -1 = 9
^^^ -1 is in the second multiplication slot bc 0 - 1 = -1
-9 x -2 = 18
^^^ -2 is in the second multiplication slot bc 0 - 2= -2
-9 x -3 = 27
^^^ -3 is in the second multiplication slot bc 0 - 3 = -3
***Remember that when you are multiplying two negative numbers the solution will be positive
Hope this helped!
