Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
- system of linear equation
<h3>let's solve:</h3>
according to the first condition
according to the second condition
Answer:
- 3/x-1
Step-by-step explanation:
8 1/9 because 9 times 8 is 72 and 73-72=1 so 8 1/9
X + (x + 1) + (x + 2) = 126
3x = 123
x = 41
So the sides are 41, 42 and 43
