Answer: The first option.


Step-by-step explanation:

1. The formula for calculate the perimeter is:

P=2l+2w

Where l is the lenght and w is the width.

2. The first perimeter is:

P_1=2(105m)+2(12.5m)=235m

3. If you multiply the dimension by a scale of factor of 2, is the same as write the following expression:

P_2=2(2l+2w)

Where 2l+2w is the first perimeter.

4. Then:

 P_2=2(235m)=470m

Answer:

First option is correct.

Step-by-step explanation:

Case first : Length =105m

                width = 12.5 m

Perimeter formula = 2 [ length +width]

                              = 2 [ 105m + 12.5m ]

                               = 2(117.5)

                               =235m

Case Second when dimensions are multiplied by 2

  Length = 2 (105m ) = 210 m

width = 2(12.5) = 25m

Perimeter = 2 [ 210+25]

                 = 2 [235]

                  = 470  m  = 2 times 235

                    perimeter is increased by factor of 2.

Answer:

A. 4x-10

Step-by-step explanation:

We see that this is a rectangle. To find the perimeter, we do L+W+L+W. So in this case, we can do (x+2)+(x-7)+(x+2)+(x-7). We can also simplify this to   2(x+2)+2(x-7)

Combine like terms now.

Simplify this to:

2x+4+2x-14

Simplify further:

4x-10

Justin drinks 1 litter of water.He drank 2,000 litters at his game.How many during his game and his practice?Explain.
djverab [1.8K]

The question is incomplete. The complete question is :

Justin drinks 1 litter of water during the soccer practice. He drank 2,000 milliliters of water at his game. How many liters of water did he drink during his game and his practice? Explain.

Solution :

It is given that :

During practice, Justine drank = 1 liter of water

During game, Justine drank = 2000 milliliters of water

We know that,

1 liter = 1000 mL

Therefore, during the game, Justine drank :

1000 mL = 1 liter

∴ 2000 mL = 2 liter

So Justine drank 2 liters of water during his soccer game and 1 liter of water during his practice.
