Answer:
x=4
Step-by-step explanation:
11x-4=5x+20
4x=16
x=4
I got a. I multiplied 0.125 by 45 and got 5.625. I then divided 5.625 by five an got 1.125. I'm not really sure about my answer, so I did it another way. I divided .125 by five and got .025 so I multiplied that by 45 and got 1.125. I multiplied 1.125 by 1000 and got A.
Nonagon - 9 sides
Sum of interior angle of a polygon is (n-2)180 = x
N is the number of sides, so when you plug in 1260 for x, you get 9 for n
Number = 125
Here, ∛125 = 5
so, in exponential form, it would be: 5³
So, your final answer is 5³
Hope this helps!
