Answer:
Angle 3 and angle 1 both equal 130 degrees because they are alternate interior angles.
f(g(x)) = x² - 2x + 1
Step-by-step explanation:
To find f(g(x)), substitute x = g(x) into f(x) , that is
f(g(x))
= f(x - 1)
= (x - 1)² ← expand using FOIL
= x² - 2x + 1
distance =12 miles
speed =4 miles per hour
Time=?
t =d/s
t= 12/4
time= 3 minutes
