Explanation:

Linear escale factor 1.

In this case the original volume of the parallelepiped is:

Volume=4*2*3=24\text{ u}^3

24 cubic units and the new volume must be:

NewVolume=\left(4*1\right)\left(2*1\right)\left(3*1\right)=24u^3

So in this case the ratio of volumes is 1:1

Linear escale factor 2.

In this case the original volume of the parallelepiped is the same: 24 cubic units.

The new voume must be:

NewVolume=\left(4*2\right)\left(2*2\right)\left(3*2\right)=8*4*6=192u^3

So in this case the ratio of volumes is 24:192, that is 1:8

Linear escale factor 3.

In this case the original volume of the parallelepiped is the same: 24 cubic units.

The new voume must be:

NewVolume=(4\times3)(2\times3)(3\times3)=12*6*9=648u^3

So in this case the ratio of volumes is 24:648, that is 1:27

Linear escale factor 4.

In this case the original volume of the parallelepiped is the same: 24 cubic units.

The new voume must be:

NewVolume=(4\times4)(2\times4)(3\times4)=16\times8\times12=1536u^3

So in this case the ratio of volumes is 24:1536, that is 1:64

Linear escale factor r.

In this case the original volume of the parallelepiped is the same: 24 cubic units.

The new voume must be:

NewVolume=(4*r)(2*r)(3*r)=4r\times2r\times3r=24r^3\text{ }u^3

So in this case the ratio of volumes is 24:24r^3, that is:

1:r^3

X = 2y-2<br> 4x-9 = 11<br><br> Step by step please
Alex787 [66]
Answer x=5, y= 3.5

Find y by plugging the x value into the 2nd equation
4(2y-2) -9=11
8y - 8 - 9 =11 combine like terms
8y = 28 divide both sides by 8
y = 3.5

Now find x
Plug your y value into first equation
X = 2(3.5) -2
X= 7-2
X=5

You can check your work by putting your x or y values into the equations

For the first equation
5=2(3.5) -2
5=5

For the second equation
4(5) -9 = 11
20 - 9 = 11
11 =11
