Answer:
7, 23, and 20
Step-by-step explanation:
Okay, let's go through this. We know that the perimeter is 50 and the perimeter must be all the sides added together. let's write that down
n + 4n - 5 + 2n +6 = 50
Let's combine like terms
7n + 1 = 50
subtract 1 from each side
7n = 49
Divide both sides by 7
n = 7
We know that one of the sides is n, so part of our answer is 7. Now let's plug in n for the other values
4(7) - 5 = 23
2(7) +6 = 20
The answer is 7, 23, and 20
