You use the formula C=2(3.14)r r is the radius and in this situation 2 so the answer will be 12.56

(x + 2)(x - 4)
= x^2 + 2x - 4x - 8
= x^2 - 2x - 8
Answer:
25.6 km/h
Step-by-step explanation:
Omani:
First, 1.5 hours = 1 hour and 30 minutes
and 66 miles = 105.6 km (66 x 1.6 = 105.6)
105.6 / 1.5 = 70.4 km/h
Omani's speed is 70.4 km/h
Adedi:
1 hour and 15 minutes is 1.25 hours
she drives 56 km in 1.25 hours
So 56 / 1.25 = 44.8 km/h
Adedi's speed is 44.8 km/h
Difference:
70.4 - 44.8 = 25.6 km/h
Omani is faster than Adedi with 25.6 km/h
2*2=4 first you multiply
4-1=3 then subtract
3+3=6 now you add and that is your answer =6
