3n≥24
divide both sides by 3
n≥8

Step-by-step explanation:
X = 18
Steps:
Remove the parenthesis...
4x-6+x = 12+4x
Then cancel out 4x...
-6+x = 12
Then regroup the terms...
x - 6 = 12
Add 6 to both sides...
x = 12 + 6
Then you get...
x = 18
Hope this helped!

5^2 + 12^2 = 169
square root of 169 is 13
the missing side length is 13 in
