Answer:
Step-by-step explanation:
For the first part:
[tex](x-7)^2=36\\\sqrt{(x-7)^2}=\sqrt{36}\\[/tex]
(x-7)=±6
so lets take +6 first
x-7=6
x=6+7
x=13
now lets take -6
x-7=-6
x=-6+7
x=1
For the second part:
[tex](x-1)^2=50\\\sqrt{(x-1)^2}=\sqrt{50}\\[/tex]
x-1=±7.07
so lets take +7.07
x-1=7.07
x=7.07+1
x=8.07
now lets take -7.07
x-1=-7.07
x=-7.07+1
x=-6.07
