Let's call that the Multiplicative Identity Property.
1 is the identity element for multiplication. Those are just fancy words for the obvious property that anything times 1 is itself.
Answer:
C) x = 0 or x = - 9
Step-by-step explanation:

<h3>
Answer: 1260</h3>
Work Shown:
We have 9 sides of this polygon. See the diagram below. So n = 9
Plug that into the formula below to find the sum of the interior angles
S = 180(n-2)
S = 180(9-2)
S = 180*7
S = 1260
Well you had x inches of snow in the beginning so
after monday it was
x+3
after wednesday
x+3+5=x+8
so the invers is the value that you use to get back to x
so if you now have x+8 than the inverse is -8
