If x + y = 12, what is the minimum value of:
√(4 + x2) + √(9 + y2)
Suppose:
x2 = 17x + y y2 = x + 17y
If x ≠ y, what is √(x2 + y2 + 1) equal to?
Solve for the parameter a for which the sum of all of the real valued roots to the equation sin(√(ax – x2)) = 0 is exactly equal to 100.
A bird has a head 9 cm long. The tail is equal to the size of the head plus a half of the size of the body. The body is the size of the head plus the tail. How long is the bird?
