Find the perimeter.

Lorico [155]

Answer:

12x+9

Step-by-step explanation:

We may find the perimeter of a shape by adding all of it's side lengths.

We can start by adding 2 sides together.

(5x+2)+(3x+8)=8x+10

Because we don't know the value of x, we can only add together the amount of times that it is multiplied.

Now we add the final side.

(8x+10)+(4x-1)=12x+9

Hope this helps friend.

Solve the problem. If at a given speed a car can travel 95.6 miles on 4 gallons of gasoline, how far can the car can travel on 6

VMariaS [17]

Answer: The correct option is (B) 1625.2 miles.

Step-by-step explanation: Given that at a given speed a car can travel 95.6 miles on 4 gallons of gasoline.

We are to find the distance that the car can travel on 68 gallons at the same speed.

We will be using the UNITARY method to solve the given problem.

Distance traveled by the car on 4 gallons of gasoline = 95.6 miles.

So, the distance traveled by the car on 1 gallon of gasoline will be

$\dfrac{95.6}{4}=23.9~\textup{miles}.$

Therefore, the distance traveled by the car in 68 gallons of gasoline is given by

$23.9\times68=1625.2~\textup{miles}.$

Thus, the required distance traveled by the car on 68 gallons of gasoline is 1625.2 miles.

Option (B) is CORRECT.
