Answer:

A) x - = -10

C) x = 4

Step-by-step explanation:

(x + 3)² = 49

(x + 3)² = 7²

Take square root both sides,

[tex]\sf \sqrt{(x + 3)^2}=\sqrt{7^2}[/tex]

    x + 3   =  ± 7

     x + 3 = +7        ; x + 3 = -7

          x  = 7 - 3     ;       x = -7 -3

          x = 4           ;        x = -10

x = 4  , -10
