Answer:
x=6
Step-by-step explanation:
7+5(×-3)=22
expand the brackets:
7 + 5x - 15 = 22
simplify:
5x - 8 = 22
add 8 to both sides:
5x = 30
divide both sides by 5
x = 6

Answer:
![\large\boxed{36\pi}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B36%5Cpi%7D)
Step-by-step explanation:
The formula of a volume of a sphere:
![V=\dfrac{4}{3}\pi R^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20R%5E3)
R - radius
We have R = 3 ?. Substitute
![V=\dfrac{4}{3}\pi(3^3)=\dfrac{4}{3}\pi(27)=(4)\pi(9)=36\pi](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%283%5E3%29%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%2827%29%3D%284%29%5Cpi%289%29%3D36%5Cpi)
If the radius is 30, then the volume is:
![V=\dfrac{4}{3}\pi(30^3)=\dfrac{4}{3}\pi(27,000)=(4)\pi(9,000)=36,000\pi](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%2830%5E3%29%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%2827%2C000%29%3D%284%29%5Cpi%289%2C000%29%3D36%2C000%5Cpi)
If 30 is the length of diameter, then the radius R = 30 : 2 = 15.
Therefore the volume:
![V=\dfrac{4}{3}\pi(15^3)=\dfrac{4}{3}\pi(3,375)=(4)\pi(1,125)=4,500\pi](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%2815%5E3%29%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%283%2C375%29%3D%284%29%5Cpi%281%2C125%29%3D4%2C500%5Cpi)
Answer: <span>2,856 ft³ .</span>

Volume of a rectangle prism = BASE AREA * height ;
The "base area" is the area of the rectangle:
(Area = length width; or, "L * w").
_______________________________________________
So, volume of a rectangular prism = L * w * h ; h = height ;
_________________________________________
V = L * w * h = 12 ft * 17 ft. * 14 ft = 2,856 ft³

yes, negative divided by a negative is positive
a negative multiplied by a negative is also positive
