Which expressions are equal to 763? i just dont want to do it 189 + 674

247 + 516

628 + 145

435 + 328

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"
