Arc length = radius* angle theta (in radians)
So angle 90 degree = 90*pi/180 radians= pi/2 radians
So arc length = 7.5* pi/2 cm = 11.8cm
So option A is correct.
Part A is asking you to substitute x for 6 and solve. Part B asks you to substitute x for -4.
Answer:
42x-27
Step-by-step explanation:
7(6x-4)+1 is your original expression. Distribute to get 42x - 28 + 1. Combine like terms and add 1 to -28, which is -27. So, 42x-27 is your answer.
