Answer:

The perimeter of a rectangle with sides 3x + 6 and -2x - 8​ will be:

P = 2x - 4

Step-by-step explanation:

We know that the perimeter of a rectangle of length 'l' and width 'w' is given by the formula

  • P = 2(length + width)

Given the sides of a rectangle

  • 3x + 6
  • -2x - 8​

As the opposite sides of a rectangle are congruent.

Therefore, we conclude that the Perimeter of a rectangle can be determined using the formula

\:P\:=\:2\left(3x\:+\:6\:+\:\left(-2x\:-\:8\right)\right)

    =2\left(3x+6-2x-8\right)

    =2\left(x-2\right)

     =2x-4

Therefore, the perimeter of a rectangle with sides 3x + 6 and -2x - 8​ will be:

P = 2x - 4

Answer:

2x - 4

Step-by-step explanation:

2(3x + 6) = 6x + 12

2(-2x - 8) = -4x -16

6x + 12 - 4x - 16 = 2x - 4

tatyana61 [14]
Is there more to this problem? By saying f(4), you'd be inputting a 4 for every variable x. There is not enough info here to answer the question.

This box can be packed with 48 units cubes. The edge length of each unit cube is 1 meter. What is the volume of the box?
Dafna1 [17]

48 m³

Step-by-step explanation:

A cube has equal length width and height

A cube in this case has length 1m meaning the width and height are also 1 m each in length.

The volume of the cube is (L * W * H) =  1 * 1 * 1 = 1 m³

If 48 of these can fit in the bigger box, then the bigger box has the volume of;

48 * 1 m³ = 48 m³
