Yeah. First we identify the coefficients of this equation A equals a half vehicles, five and cycles, too. Next we substitute A B and C. With their values into this formula, the denominator is two times uh the numerator is minus five present miners square road, five squared miners four times a half times two, which vehicles minus five plus, um, miners the square root of 21. If we use a calculator, their approximate values minus nine points five 83 miners horns, 417
