Answer 1

A and B

Explanation:

Answer 2

Explanation:

For the first part:

`(x-7)^2=36\\√((x-7)^2)=√(36)\\`

(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:

`(x-1)^2=50\\√((x-1)^2)=√(50)\\`

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
