Answer:
the answer is 9.7×10 to the fourth power
Step-by-step explanation:
Any decimal lower that .5 is rounded down, and anything .5 or higher is rounded up, so the answer would be 38.
Answer:
x=4/7
Step-by-step explanation:
6 - 2/3(x+5) = 4x
First I want to clear the fraction so I will multiply everything by 3
3*6 -3* 2/3(x+5) = 3*4x
18 - 2(x+5) =12x
Distribute
18 - 2x-10 =12x
Combine like terms
8 -2x = 12x
Add 2x to each side
8 -2x+2x =12x+2x
8 = 14x
Divide each side by 14
8/14 =14x/14
8/14=x
Divide top and bottom by 2
4/7=x
The answer is;
x(x+4)(x-4)=500
I don't know how it is, I just guess and it works
Answer:
The center of circle is 
Step-by-step explanation:
We need to find the center of the circle of the equation 
Since, the general equation of circle is 
Where (h,k) is center of circle and r is radius.
Re-write the circle equation is as,
Compare with
so, 
Hence, the center of circle is
