a simple way to do away with denominators, is we can simply multiply both sides by the LCD, in this case the LCD is 3, so let's multiply both sides by 3.
![\bf 3\left( \cfrac{1}{3}x+y \right)=3(4)\implies x+3y=12\implies 3y=12-x \\\\\\ y=\cfrac{12-x}{3}\implies \stackrel{\textit{distributing the denominator}}{y=\cfrac{12}{3}-\cfrac{x}{3}}\implies y=4-\cfrac{1}{3}x](https://tex.z-dn.net/?f=%5Cbf%203%5Cleft%28%20%5Ccfrac%7B1%7D%7B3%7Dx%2By%20%5Cright%29%3D3%284%29%5Cimplies%20x%2B3y%3D12%5Cimplies%203y%3D12-x%0A%5C%5C%5C%5C%5C%5C%0Ay%3D%5Ccfrac%7B12-x%7D%7B3%7D%5Cimplies%20%5Cstackrel%7B%5Ctextit%7Bdistributing%20the%20denominator%7D%7D%7By%3D%5Ccfrac%7B12%7D%7B3%7D-%5Ccfrac%7Bx%7D%7B3%7D%7D%5Cimplies%20y%3D4-%5Ccfrac%7B1%7D%7B3%7Dx)
Answer:
158
Step-by-step explanation:
5*8=40
8*3=24
3*5=15
Each of these measurements gets added twice, becasue there are 6 faces on a rectangular prism.
40 + 40 + 24 + 24 + 15 + 15 = 158
The answer to this problem is 9 hopefully this helps you!
