-18x
you first times the numbers, which becomes -18
Next you add the exponent from the veriables (x) (if you're diving you're subtractiong example: x^a/x^b = x^a-b)
Sooo when you add them you get 8-7=1 which means.. x^1 (but you don't need to put the 1)

Answer:
The picture just shows the beginning logic. We now know that we need to find a polygon with an interior angle that has a ratio of 1:3 with its exterior angle.
We can use this formula to find the number of sides of the polygon:
((n-2)×180)/n = 120
(n-2)×180 = 120n
180n - 360 = 120n
60n = 360
n = 6
We now know that the shape has 6 sides with 120 degree interior angles.
A shape with 6 sides is a hexagon.
The fraction 78/10,000 as a decimal would be 0.0078.
