Answer:
6, 21, and 23 inches
Step-by-step explanation:
The perimeter of a triangle is equal to the sum of all side lengths in that triangle. We're given the perimeter as 50 inches, and the side lengths as n, 3n + 3, and 2n + 11.
- This means that we can algebraically solve the equation
Step 1: Combine like terms.
Step 2: Subtract 14 from both sides.
Step 3: Divide both sides by 6.
Step 4: Plug in the value of n as 6 in each side.
Therefore, the side lengths are 6, 21, and 23 inches.

You place the smaller number or single number on the left side of the box then on top of the box for the first square you would take the first number of your two digit number turn that into a whole number then the second number you would put on top of the second box then just multiply them both separately then add them together.
Example number one: first multiply 5x60 you get 300 for the first box then you multiply 5x6 you get 30 so then you would add the 300 and the 30 to get 330. Hope this helps :)
