Answer:
x=12
Step-by-step explanation:
(9x-4)+(5x+16)=180
14x+12=180
-12 -12
14x=168
then devide both sides by 14
x=12
Shouldn't the equation read " (x - 4)² = 81 ", instead of "(1 - 4)² = 81" ?
If so, then the solutions are x = -5 and x = 13 .
If it's really "(1 - 4)² = 81", then that's not even an equation, and there's no solution.
