Answer:6
Step-by-step explanation:
If we know that the formula of a rectangular prism is length * width * height, and we know the height and width are 7 and 9, the length is the only thing that is left. The volume is 378, and so now we have:
length * 7 * 9 = 378. Dividing the 9 and 7, we get 378/(9*7). The length is 6.
The way you do this is by creating a system of equations:
5x - 10 = 4x + 12
Then you solve the system:
5x - 4x = 12 + 10
x = 22
Substitute x back into DEC and you get (4(22) + 12)<span>°
Which is 100</span><span>°
