A^2 + b^2 = c^2
a = 9
b = 12
Then calculate for c
If you want just the LCM it’s 2
The algorithm is tripping! It won't let me post a legit explanation. Sorry!
Subtract 6 from both sides, you get 1/3x=-14
Now multiply both sides by there, hence x=-42
Use the formula a squared plus b squared =csquared in this case you will come out with an equation like this
3sqaured + bsqaured =12squared
9+bsqaured =144
144-9= b= 135
B=approximately 11.5
