Question

√(x + 5) = √784 – √625
y(27 – y) = 182

  • A) X > Y
  • B) X < Y
  • C) X ≥ Y
  • D) X ≤ Y
  • E) X = Y or relation cannot be established
Solution

B. X < Y
Explanation:
√(x + 5) = √784 – √625
x + 5 = 9 => x = 4
y(27 – y) = 182
y = 13, 14

B. X < Y
Explanation:
√(x + 5) = √784 – √625
x + 5 = 9 => x = 4
y(27 – y) = 182
y = 13, 14
