Answer:
Step-by-step explanation:
3.5
x2 - x - 12 is the Quadratic Polynomial Whose zeroes are -3 and 4.
3,200 centimeters
12 meters represent 1,200 centimeters.
Therefore, the perimeter in centimeters is : 2*1,200+2*400=2,400+800=3,200 centimeters.
(x/3) - 3 = f^-1(x)
y = 3x-9
x = 3y-9
x - 9 = 3y
(x/3) -(9/3) = y
