A retanglular athletic field has an area of 40x2+190x-50. The width of the field is 8x-2. What is the length of the athletic field?

Respuesta :

Length = Area/Width
Length = 40x2+190x-50 / 8x - 2
Length = 10(4x2+19x-5) / 2(4x - 1)
Length = 5(4x2+19x-5) / (4x - 1)
Length = 20x2 + 95x - 25 / 4x - 5
Length = 5x + 25
