Answer:
So,
approximate solutions are x = 124.32 and x = 117.68
[tex]exact \: \: solutions \: \: are \\ \: \: x \: = \: \: - \sqrt{11} + 121 \: \: \: \\ and \: \: x \: = \sqrt{11} + 121[/tex]
Step-by-step explanation:
13(x-121)²=143
or, (x-121)² = 11
[tex]x - 121 = \sqrt{11} \\ x = \sqrt{11} + 121[/tex]
so, x = 124.32
OR,
[tex]x = - \sqrt{11} + 121[/tex]
so, x =117.68
for exact solutions,
[tex]x = - \sqrt{11} + 121[/tex]
[tex]x = \sqrt{11} + 121[/tex]
