Acircle is centered at (3, 8) and is tangent to the x-axis. write its equation in standard form. a) (x - 3)2 + (y - 8)2 = 9 b) (x + 3)2 + (y + 8)2 = 9 c) (x - 3)2 + (y - 8)2 = 64 d) (x + 3)2 + (y + 8)2 = 64

Step-by-step explanation:

A circle is centered at (3, 8) and is tangent to the x-axis. Write its equation in standard form.

A)(x - 3)2 + (y - 8)2 = 9<==2x+2y=31

C)(x - 3)2 + (y - 8)2 <==2x+2y=86

D)(x + 3)2 + (y + 8)2 = 64<==2x+2y=42

the answer is B
