Want me to show this, or did you just want the answer?
![-4^4](https://tex.z-dn.net/?f=-4%5E4)
when we have an exponent means that the base is multiplied times the number that is as the exponent, since there is no parentheses the exponent only affects the 4
![-(4)^4=-1\cdot4\cdot4\cdot4\cdot4](https://tex.z-dn.net/?f=-%284%29%5E4%3D-1%5Ccdot4%5Ccdot4%5Ccdot4%5Ccdot4)
interior angle of a regular 18-gon.
It is easier to calculate the exterior angle of a regular polygon of n-sides (n-gon) by the relation
exterior angle = 360/n
For a 18-gon, n=18, so exterior angle = 360/18=20 °
The value of each interior angle is therefore the supplement, or
Interior angle = 180-20=160 degrees.
Naming of a 9-gon
A polygon with 9 vertices is called a nonagon (in English) or enneagon (French ennéagone, but the English version is sometimes used)
You had a good start with the correct answer.
Exterior angle of a 15-gon
The exterior angle of a 15-gon can be calculated using the relation given in the first paragraph, namely
Exterior angle = 360/15=24 degrees
Answer:
100+x
Step-by-step explanation:
Peter starts out with 100 dollars and then gets X more meaning we have to add X to what he originally had and that looks like this 100+x
