When looking at a rectangular prism, we know that Volume = length * width * height
If we are given that the volume of the prism is 280 cubic meters (m^3), the length is 8 meters, and the width is 7 meters, we can fill in our equation.
280 = 8 * 7 * height
280 = 56 * height
Because we are solving for the height, we divide both sides by 56
280/56 = height
height = 5 meters
I do believe it is the second one
Note that multip. 10 by 2 results in 20; mult. 20 by 2 results in 40, and so on. So the common ratio is 2.
Answer:
7x-34 because...
product means multiply the variable x by 7
7x
decreased mean we subtract 34 from 7x
7x-34
