Solve the radical equation. square root of 25 minus 40 x end root is equal to x minus 10 Which is the true solution?

For the square root to be defined, 25 − 40x must be at least 0, so x ≤ 5/8. Also, the square root is nonnegative, so x − 10 must be at least 0, which requires x ≥ 10. No number can satisfy both conditions, so there are no true solutions (choice A).
