Step-by-step explanation:
Ответ:
(a) the quadratic equation that would best represent the given is,
(w)(w + 4) = 525
w² + 4w = 525 or w² + 4w - 525 = 0
(b) solving for the values of w in the quadratic equation,
w = 21 and w = -25
thus, we take w as 21 and w+4 = 25. the dimensions of the floor are therefore 21ft and 25 ft.
