We calculate the sum of all interior angles using this formula 180(n-2) , n=number of sides
180(40-2)= 6840
6840 ÷ 40 = 171
D because the x-intercept would be 1/3, not 3

Answer:
2.2 (rounded)
Step-by-step explanation:
Answer:
3126
Step-by-step explanation: f(1)=6 and f(n)=5f(n-1)-4. This means that next number is 5 times previous number minus 4.
f(2)=5f(1)-4 =5x6-4 = 30-4 = 26
f(3)=5f(2)-4 =5x26-4 = 130-4 = 126
f(4)=5f(3)-4 =5x126-4 = 630-4 = 626
f(5)=5f(4)-4 =5x626-4 = 3130-4 = 3126
