Solve for x, 12y+6=6(y+1)

Vanyuwa [196]

For this case we must solve the following equation:

$12y + 6 = 6 (y + 1)$

We apply distributive property on the right side of the equation:

$12y + 6 = 6y + 6$

We subtract 6y on both sides of the equation:

$12y-6y + 6 = 6\\6y + 6 = 6$

We subtract 6 from both sides of the equation:

$6y = 6-6\\6y = 0$

Dividing by 6 on both sides of the equation:

$y = 0$

So, the result is $y = 0$

Answer:

$y = 0$

The two rectangular prisms are similar.

Sophie [7]

Answer:

The volume of the larger rectangular prism is $648\ cm^{3}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

x-----> the volume of the larger rectangular prism

y-----> the volume of the smaller rectangular prism

$z^{3}=\frac{x}{y}$

In this problem we have

$z=\frac{12}{4}=3$ ---> the scale factor is equal to the ratio of its corresponding sides

$y=24\ cm^{3}$

substitute and solve for x

$3^{3}=\frac{x}{24}$

$x=27*24=648\ cm^{3}$
