Answer:
x = 5 and x = 
Step-by-step explanation:
To find the zeros equate f(x) to zero, that is
(2x - 1)(x - 5) = 0
equate each factor to zero and solve for x
2x - 1 = 0 ⇒ x =
x - 5 = 0 ⇒ x = 5
Answer: the length of the field is 70 yards. The width of the field is 35 yards
Step-by-step explanation:
Let L represent the length of the rectangular athletic field.
Let W represent the width of the rectangular athletic field.
A rectangular athletic field is twice as long as it is wide. This means that
L = 2W
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
If the perimeter of the athletic field is 210 yards, it means that
210 = 2(L + W)
L + W = 210/2 = 105
Substituting L = 2W into L + W = 105, it becomes
2W + W = 105
3W = 105
W = 105/3 = 35
L = 2W = 2 × 35
L = 70
