Ответ:
x = 142
Step-by-step explanation:
√x+2 - 15 = -3 (Given)
√x+2 = 12 (Add 15 on both sides)
x + 2 = 144 (Square both sides to get rid of the radical)
x = 142 (Subtract 2 on both sides)
Ответ:
Step-by-step explanation:
sqrt(x + 2) - 15 = -3
sqrt(x + 2) = 12 (add 15 to both sides)
x + 2 = 12² = 144 (square both sides)
x = 142.
