An airplane lands at an airport 60 miles east and 25 miles north of where it took off. how far are the two airports?

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

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4
