Answer:
the -3 is being distributed. --> the 5 stays outside till the end. multiply the 3 inside first, then the negative. and then add the 5 to the final answer
5-3(d+21) = -->> 5-(3d+21)=--->>>5-3d-21=3d-16
Step-by-step explanation:
5-3(d+21) =
5-(3d+21)=
5-3d-21=
ans=3d-16

Answer: TRUE
Step-by-step explanation: The number 3 is an upper bound because use 3 as a multiplyer of each bcoefficient of the polynomial and at each multiple,subtract the next coefficient from it. if all result after subtraction show positive, then the number used is an upper bound. This method is known as the synthetic division.
3 3 -5 -5 5 2
0 9 12 21 78
3 4 7 26 80
It took him 9.92 hours to complete the journey.
Step-by-step explanation:
Given,
Distance traveled = 50 miles
Distance traveled on horse = 
Distance traveled on foot = 25 miles
Speed while riding = 9 miles per hour
Distance = Speed * Time
Time while riding = 
Time while riding = 
Speed while waling = 3.5 miles
Time = 
Total time = 2.78+7.14 = 9.92 hours
It took him 9.92 hours to complete the journey.
