Question

A. x + 11
B. x − 11
C. x − 22
D. x + 22

I got d please correct if wrong thx.

Answer 1

(x-11)^2 = r^2 = x^2 - 22 x + 121
so I do not get d

Answer 2

what is it then?

Answer 3

hint:
(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²

Answer 4

I'm confused what it it?

Answer 5

I got B I am an current math student.

Answer 6

The correct answer is B you dumb idiot
